DRAFT: preliminary version of Oneiric Release Notes

Introduction

These release notes for Ubuntu 11.10 (Oneiric Ocelot) provide an overview of the release and document the known issues with Ubuntu 11.10 and its variants.

Release Overview

Oneiric Ocelot includes new releases of all major flavors of Ubuntu: desktop, server, cloud, Kubuntu, Xubuntu, Lubuntu, Edubuntu, Mythbuntu, and Ubuntu Studio. For Ubuntu, this release provides a full [http://unity.ubuntu.com/ Unity] experience, even without 3D hardware acceleration, promoting Unity 2D to the primary fallback shell. LightDM steps forward as the login manager for Ubuntu, Edubuntu, Xubuntu, Mythbuntu, and Ubuntu Studio. It also includes a customized Unity greeter. Kubuntu showcases the best and the newest features of the KDE Platform, Plasma Workspaces, and Applications (including the Muon Software Centre). Ubuntu Server introduces a technical preview of Juju - a modern approach to service deployment and orchestration on cloud and bare metal environments, and support for the ARM architecture.

Ubuntu

New Features

Lenses and Interface Changes

11.10 includes a new release of [http://www.compiz.org compiz] and [http://unity.ubuntu.com Unity]. Highlights of this release are:

• A new Alt+Tab switcher.
• "Places" are renamed to "Lenses". This feature now also integrates multiple sources and advanced filtering options like ratings, range, and categories.
• The Dash has a new music lens, linked to Banshee, that searches your personal and online music collections.
• Better performance of launchers and panel, ported to GTK 3 and GTK 3-based indicator stack.
• Full support for Chinese, Japanese, Korean, and other script languages.

Unity 2D reduces the delta with Unity, shares more code with it, and has an almost completed [ http://ubuntuaccessibility.wordpress.com/2011/10/13/oneiric-ocelot accessibility support] set of features. See [#Known_issues known issues] for the missing accessibility parts.

The indicators got a visual refresh that includes a refactoring of the session indicator and a new power indicator.

The [http://font.ubuntu.com/ Ubuntu Font Family], developed under the guidance of the [http://www.daltonmaag.com Dalton Maag] type foundry and the [http://design.canonical.com Canonical design team], has been expanded with Ubuntu Mono and Ubuntu Condensed.

Revised Software Center

The Ubuntu Software Center now features a "top rated" section on the main category page and all subcategory pages. Standalone .deb installation is now significantly faster. Full CJK support is also available.

OneConf is now built in to keep your installed applications in sync between computers. To activate it, use "File → Sync between computers…".

New ARM subarchitectures

Ubuntu 11.10 is introducing two new desktop images for ARM subarchitectures: armel+ac100 for the Toshiba ac100 netbook (NVIDIA Tegra 2 SoC), and armel+mx5 targeted at the Freescale i.MX53 Quick Start development board. Both of these images are "best-effort" community-supported images aimed at developer and hobbyist use.

Revised DVD content

In Ubuntu 11.10 there is now a revised, smaller (in size) DVD based on community feedback over the last few cycles. This new DVD has a more manageable size of 1.5G. The new DVD image is an extension of our current CD image that includes all the language packs and some other useful applications, such as Inkscape, GIMP, Pitivi, and a more complete LibreOffice suite. All the packages that used to be on the DVD are still available from the archive.

New App Developer Site

Coinciding with the Ubuntu 11.10 release, a significant milestone in the ongoing effort of making Ubuntu a target for application developers has also been reached: the Ubuntu App Developer site launch.

[http://developer.ubuntu.com developer.ubuntu.com] should now be the central point of reference for any topics related to Ubuntu application development. From creation to publication: porting, sharing, contributing, and finding information. This site should grow organically to provide the tools, share knowledge, and act as the springboard for fostering application proliferation and developer community growth.

Read more in the [http://developer.ubuntu.com/2011/09/announcing-the-ubuntu-app-developer-site/ official announcement].

New Localized ISO Tools

A set of tools for Ubuntu LoCo teams to create custom images to provide an experience even closer to the culture of the region they cover are now available. After setting the foundations in Ubuntu 11.10, in the next cycle we plan to work with the community on expanding community usage. [../LocalizedImagesRollout Learn more].

Updated Applications

[http://www.mozilla.org/thunderbird/ Thunderbird] is included as the default email client. This now includes menu and launcher integration via Unity.

Backups are easy in Ubuntu 11.10 now that [http://live.gnome.org/DejaDup Déjà Dup] is included as the default backup tool. Securely store copies of your important data on a separate hard drive, cloud server, or even Ubuntu One.

The new [http://gwibber.com/ Gwibber] landed in Oneiric, brings improved performance and a new interface using the most recent GNOME technologies.

[http://library.gnome.org/misc/release-notes/3.2/ GNOME 3.2] is included and is a major upgrade from GNOME 2.32 included in Ubuntu 11.04. GNOME Classic is no longer installed by default, but can be enabled after installation completes by installing gnome-panel. Note that the indicator status menus have not yet been ported to the new gnome-panel and the default upstream panel layout is used instead of the heavy Ubuntu customizations. GNOME Shell is also available for install.

Ubuntu now uses the [http://www.freedesktop.org/wiki/Software/LightDM LightDM] login manager with the Unity greeter.

Synaptic and Pitivi are no longer included in the default install but are still available in the Ubuntu repositories.

Ubuntu Server

New Features

[http://wiki.ubuntu.com/ServerTeam/Orchestra Orchestra] is a collection of the best free software services for provisioning, deploying, hosting, managing, and orchestrating enterprise datacenter infrastructure services, by, with, and for the Ubuntu Server available in 11.10. Orchestra enables users to quickly deploy a solution in the datacenter. Instead of manually setting up a complex network installation environment, users can now leverage Orchestra to rapidly deploy new servers in production using the best open-source tools. The process is standardized and fully automated and thus minimizes manual intervention and ensures consistency. This solution is provided as a response to all those user requests that we received for making multiple installs and deployments easier.

The core component of Orchestra provisioning is [https://fedorahosted.org/cobbler/ Cobbler], which has been receiving significant attention.

[http://juju.ubuntu.com Juju] is available in Ubuntu 11.10 as a technical preview. Juju is a critical part of Ubuntu Server that is designed to handle service deployment and coordination for both cloud and bare metal. It has many [http://launchpad.net/charm Charms] available (including [http://www.openstack.org/ OpenStack] deployment - primarily for bare metal deployments). While the development team uses Juju on a regular basis, it is still under heavy development and changing rapidly, however the included snapshot is enough to get you started and testing [http://juju.ubuntu.com Juju] in a development environment. Currently, it is recommended that you do not use Juju in production systems. However, you can use Juju via the regular snapshot releases that will be provided [https://launchpad.net/~juju/+archive/pkgs here]. Additionally, it is highly recommend that you follow development reports of Juju posted [http://cloud.ubuntu.com here] to be aware of changes to [http://juju.ubuntu.com Juju] over the next few months.

Ubuntu Server 11.10 is the first release with support for the ARM architecture. ARM architecture is typically presumed to be used in embedded or mobile devices, but in recent years ARM architecture has advanced tremendously. ARM processors are now able to handle workloads traditionally done by Intel and AMD based servers. In the last cycle, the Ubuntu Server team worked closely with the Ubuntu ARM team and the ARM partners (interested in the ARM server market), to produce the technical preview of Ubuntu Server for ARM.

Updated Applications

Former UEC components (including Eucalyptus) are no longer part of the CD image and are no longer included in the security-supported main component of the archive. An upgrade path is provided from from 11.04.

The [http://xen.org/ Xen hypervisor] has now been reintroduced as an option in Ubuntu Server.

Ubuntu Cloud

Ubuntu 11.10 introduces the new Ubuntu Cloud Infrastructure and Ubuntu Cloud Guest images. The [https://cloud-images.ubuntu.com Cloud Infrastructure images] are the successor of the Ubuntu Enterprise Cloud and provide a ready to deploy Infrastructure-as-a-Services (IaaS) based on the [http://wiki.openstack.org/ReleaseNotes/Diablo Openstack Diablo release]. Ubuntu Cloud Guest was previously known as Jeos or UEC-image. This Ubuntu Server image is specially tailored for use in a public or private cloud instance. ARM cloud images are also being built. However, currently no cloud infrastructure can consume ARM cloud images properly. Therefore, these images are available on a best effort basis.

More information is available at https://cloud-images.ubuntu.com.

Ubuntu Common Infrastructure

Hybrid CD/USB images supported

32-bit compatibility on amd64 systems

Ubuntu 11.10 provides "multiarch" support for installing 32-bit library and application packages on 64-bit systems. For all amd64 installs and upgrades, select 32-bit software (like Skype and Flash), will now be installable directly using the same 32-bit packages that are used on i386 installations. You are not required to install the ia32-libs compatibility package. For users, this change means that the 32-bit libraries will always be available at the same time as their 64-bit counterparts, even in the case of security updates, and users will only need to install those 32-bit libraries required by the user's application(s).

Linux 3.0 Kernel

Ubuntu 11.10 includes the 3.0.0-12.20 Ubuntu kernel which brings the 3.0 upstream kernel, the latest mainline release. The Ubuntu kernel is based on the linux v3.0.4 [http://kernel.org upstream stable kernel].

This kernel update brings a number of performance improvements both to ext4 (the default filesystem) and the process scheduler. This enhancement will improve interactive behavior and introduce support for newer hardware.

For the server, the kernel also brings the return of Xen dom0 support as a tech preview building towards full support for the 12.04 LTS Release. It also has container and namespace improvements enabling full LXC support which is of particular interest on ARM platforms. There are also a number of networking and netfilter improvements.

A note to application developers, the default number of file descriptors has been increased to simplify management of those programs that utilize very large numbers of files.

For the deeply technical, there are improvements to TCP and fragment identifier generations, btrfs has a number of significant improvements, ext4 has SMP scalability improvements, and the Big Kernel Lock is dead!

GCC 4.6 Toolchain

Ubuntu 11.10 includes gcc 4.6 as the default compiler. The GCC packages are built from the 4.6-2011.07 [https://launchpad.net/gcc-linaro Linaro GCC] release based on the [http://gcc.gnu.org/gcc-4.6/changes.html GCC 4.6.1 release]. See [https://wiki.ubuntu.com/ToolChain/CompilerFlags ToolChain/CompilerFlags] for a summary of compiler defaults which are different from the upstream release.

The compiler passes by default two additional flags to the linker:

-Wl,--no-copy-dt-needed-entries

Also known as --no-add-needed. First enabled in Ubuntu 11.04 (but disabled in the final 11.04 release), and permanently enabled in Ubuntu 11.10. This option affects the treatment of dynamic libraries referred to by DT_NEEDED tags inside ELF dynamic libraries mentioned on the command line. This option also has an effect on the resolution of symbols in dynamic libraries. This will be the default in the upcoming binutils-2.22 release.

This may result in build errors. More information and recipes how to fix such build errors can be found at NattyNarwhal/ToolchainTransition and [http://wiki.debian.org/ToolChain/DSOLinking#Not_resolving_symbols_in_indirect_dependent_shared_libraries the corresponding Debian page].

-Wl,--as-needed

First enabled in Ubuntu 11.04 (but disabled in the final 11.04 release), and permanently enabled in Ubuntu 11.10. With this option the linker will only add a DT_NEEDED tag for a dynamic library mentioned on the command line, if if the library is actually used.

A common build error with this option enabled is seen when libraries appear on the command line before objects referencing these libraries. More information and recipes how to fix such build errors can be found at NattyNarwhal/ToolchainTransition and [http://wiki.debian.org/ToolChain/DSOLinking#Only_link_with_needed_libraries the corresponding Debian page].

Python

Default and available versions of Python have been updated as follows:

• Default: 2.7.2 (Natty had 2.7.1)
• Available: 2.6.7 (Natty had 2.6.6)
• Available: 3.2.2 (Natty had 3.2)

Python 3.1 has been removed (3.1.3 was available in Natty).

The primary work done on Python this cycle was internal/developer-focused and not user visible. We made the transition to [https://blueprints.launchpad.net/ubuntu/+spec/foundations-o-dhpython-transition the dh_python2 helper] for packaging Python libraries and applications. Previous Python helpers have all been deprecated in Debian, and in Oneiric, all Python packages on all of our CD images now use the best-of-breed dh_python2.

Ubuntu Core

Ubuntu Core is a new minimal rootfs for use in the creation of custom images for specific needs. Developers will now be able to use Ubuntu Core as the basis for their application demonstrations, constrained environment deployments, device support packages, and other goals. More information is available on the [https://wiki.ubuntu.com/Core Ubuntu Core wiki page].

Ubuntu One

The new music lens in the Dash supports searching your personal and online music collections, as well as the Ubuntu One Music Store.

The [http://live.gnome.org/DejaDup Déjà Dup] backup tool, shipped by default in Ubuntu, supports backing up to the Ubuntu One cloud.

Ubuntu One music collections are now streamed to Android and iOS devices, as well as supporting file sharing cross-platform compatibility with Windows.

Kubuntu

Kubuntu 11.10 brings together lots of exciting new development from the KDE community and Kubuntu team. Some of the highlights of the release are listed below, and more details can be found in the [OneiricOcelot/Final/Kubuntu Kubuntu 11.10 announcement].

New from the KDE community

Plasma and Applications 4.7.1

[http://kde.org/announcements/4.7/ The latest stable release of KDE's Plasma Workspaces and Applications] brings new features and improvements all around. Highlights include:

• Visual updates include a new Oxygen icon theme
• A cleaner default look to Dolphin
• Gwenview's new ability to compare two or more images
• New breadcrumb feature in the Kickoff menu that simplifies navigating submenus
• More improvements in the Network Management widget

More details can be found in the [http://kde.org/announcements/4.7/plasma.php plasma 4.7 announcement] and the [http://kde.org/announcements/4.7/applications.php applications 4.7 announcement].

KDE Personal Information Management Suite 4.7

Kubuntu 11.10 introduces the new KDEPIM suite, which includes the Kmail 2 application. The look and feel is familiar to previous versions, but under the hood, most of the applications have been updated to use the [http://userbase.kde.org/Glossary#Akonadi Akonadi] storage service. This will enable better email, calendar, and other PIM activities moving forward.

IMPORTANT: This is a major upgrade to the mail, calendar and addressbook systems, and still needs usage and migration testing. While loss of data should not be an issue, it is highly recommended to back up all important data, mail, contact information, and calendars if you plan to upgrade to 11.10. Migration information can be found [OneiricOcelot/Final/Kubuntu/Kmail2 here].

Amarok 2.4.3

This new and improved version of the default music player features native support for remote NFS and SMB/CIFS collections, a better looking user interface, support for gpodder.net, as well as vastly improved reliability.

For more information have a look at the release announcements of Amarok for versions[http://amarok.kde.org/en/releases/2.4.1 2.4.1] and [http://amarok.kde.org/en/releases/2.4.3 2.4.3]

Technical Preview of OpenGL ES Powered Desktop Effects

For those adventurous and curious, Kubuntu 11.10 has packaged the work towards using a more compatible and reliable version of OpenGL, [http://en.wikipedia.org/wiki/OpenGL_ES OpenGL ES]. This new technology is particular interesting in the not so distant future for mobile devices.

New from the Kubuntu team

Muon Suite 1.2

The Kubuntu team is proud to present our new suite of tools for installing and managing software. Installing of .deb packages, updating, and software management is all part of this new, integrated suite, specifically designed to work with Debian style package management.

• Muon Software Center: Accessing thousands of free applications for your computer has never been easier. The Muon Software Center provides an easy-to-use way to access extra applications, games and accessories to further customize your desktop. Applications come with ratings and reviews for each application from the wider Ubuntu community, as well as with screenshot previews to help you make informed decisions.

• Muon Package Manager: For the budding system administrator, the Muon Package Manager provides a powerful feature set with a usability-driven interface. With its lightning-fast quick-search and extensive filtering abilities, you should have no trouble finding exactly the right package. From selective upgrades to package pinning to mass package removal, the Muon Package Manager should give you every tool you need to quickly and efficiently administer your system.

Updated Applications

TO DO: work with ScottK to fill in

Xubuntu

TO DO: work with charlie-tca to insert overview comments

New Features

gThumb is now in the default Xubuntu 11.10 installation, to help users with image transformations and viewing.

leafpad is the new default text editor (instead of mousepad), and now includes the ability to print.

pastebinit is now included in Xubuntu 11.10 installations by default. If you need to use http://paste.ubuntu.com/, you can use pastebinit in terminals to paste directly without copying and pasting the data.

LightDM is the new application that manages logins in Xubuntu 11.10.

Updated Applications

Onboard (the onscreen keyboard) is now included in the default Xubuntu menus, under Accessories. For those who require an onscreen keyboard, this will be much easier to access using only a mouse or touchpad.

Lubuntu

Lubuntu 11.10 is a brand new flavor of Ubuntu based on the Lightweight X11 Desktop Environment (LXDE) as its default GUI. The goal is to provide a very lightweight distribution, with all the advantages of the Ubuntu world (repositories, support, etc.). Lubuntu is targeted at "normal" PC and laptop users running on low-specification hardware. The target user group for this flavor will be either those users who might not be proficient in using command line tools or those users who might not have enough resources for all the bells and whistles of the "full-featured" mainstream distributions.

With many LXDE components, [http://lubuntu.net Lubuntu] also uses well-known applications, such as Chromium, Openbox, Pidgin, to name a few. The [https://wiki.ubuntu.com/Lubuntu Lubuntu project wiki] contains more information on the project and the [https://wiki.ubuntu.com/Lubuntu/Applications applications used] available.

Edubuntu

Edubuntu 11.10 inherits all the changes that occurred in the Ubuntu desktop.

This release of Edubuntu is better translated than ever before with all of our tools fully supporting translation.

If you want to try Edubuntu 11.10 without having to download our DVD, you can try it online on WebLive: http://www.edubuntu.org/weblive

To learn more about Edubuntu 11.10, go to: http://www.edubuntu.org/.

New Features

There is a refreshed look and feel with new wallpaper and login screen.

The default desktop environment is now Unity with fallback to Unity 2D when the hardware doesn't support running the 3D version. Gnome 3 Fallback (which uses an updated gnome-panel) is available for those who want it as an option in the installer.

Updated Applications

Updates in this release include:

• gobby was updated to gobby-0.5.

• gbrainy was updated to the latest and greatest version 2.

Default changes include:

• Nanny, Pessulus and Sabayon haven't been ported to Gnome 3.0/dconf yet and were consequently dropped from the default installation.

Mythbuntu

11.10 is not a feature heavy release, but does bring in new HW support from the updated kernel and graphics stack. It is leading up in preparation for the new Mythbuntu release strategy, LTS only releases starting with 12.04.

New Features

LightDM is the new application that manages logins in Mythbuntu 11.10.

Chromium has been adapted by the Mythbuntu team to replace Firefox by default.

Ubuntu Software Center is now the default software installer instead of Synaptic, in line with the rest of Ubuntu.

Updated Applications

MythTV has been updated to more recent builds. While MythTV is still on the 0.24 series, it has been growing more stable with each new build.

Ubuntu Studio

Ubuntu Studio 11.10 is still working through our XFCE transition, so some items or features might not be completely resolved yet.

More details can be found at: [UbuntuStudio/11.10release_notes]

New Features

LightDM is the new application that manages logins in Ubuntu Studio 11.10 and has a new background.

The menu will be different as the Ubuntu Studio team is moving towards a more DE agnostic way of handling categories and submenus.

The icon set has changed.

Updated Applications

Many non-A/V/G specific applications, text editor for example, have changed to XFCE equivalent. Unfortunately, because of low resource bandwidth the Ubuntu Studio Team was not able to complete the testing in this cycle and therefore deficiencies are expected and we apologize in advance.

Installation

Overview

Preparing your computer for Ubuntu is now much simpler, with a wider range of disk setup options. Each of these are detailed at length to provide you with a clear understanding of the actions that will take place with your selection.

You can now reinstall or upgrade an existing copy of Ubuntu with the Desktop CD installer, provided that your computer is connected to the Internet.

Download

Ubuntu 11.10 images can be downloaded from a location near you:

• http://www.ubuntu.com/download (Ubuntu and Ubuntu Server) .

System Requirements

The minimum memory requirement for Ubuntu 11.10 is 384 MB of memory for Ubuntu Desktop. Note that some of your system's memory may be unavailable due to being used by the graphics card. If your computer has only the minimum amount of memory, the installation process will take longer than normal; however, it will complete successfully, and the system will perform adequately once installed.

The minimum memory requirement for Ubuntu Server 11.10 is 128 MB of memory.

Systems with less memory may be able to select "Install Ubuntu" from the boot menu to run just the installer, rather than the whole desktop, or may be able to use the alternate install CD.

Upgrading

Upgrading from Ubuntu 11.04

To upgrade from Ubuntu 11.04 on a desktop system, press Alt+F2 and type in "update-manager -d" (sans quotes) into the command box. Update Manager should open up and display following message: "New distribution release '11.10' is available. Click Upgrade and follow the on-screen instructions".

To upgrade from Ubuntu 11.04 on a server system, follow the steps listed below: Step 1: Install the update-manager-core package (if it is not already installed). Step 2: Use following command sudo do-release-upgrade -d to launch the upgrade tool. Step 3: Follow the on-screen instructions. Note that the server upgrade is now more robust and will utilize GNU screen and automatically re-attach in case of dropped connection problems, for example.

Upgrading from Other Releases

Users of other Ubuntu releases need to upgrade first to 11.04, and then to 11.10.

For further information on upgrading to 11.04, please see the instructions in: https://help.ubuntu.com/community/NattyUpgrades

Known issues

The issues we know about at this point (and some of the workarounds), are documented here so you don't need to spend time reporting these bugs again:

Boot, installation, and post-installation

• When overwriting an existing installation in the Ubiquity desktop installer, it creates a new swap partition instead of re-using the already existing one. (Bug:782507)

• Ubiquity desktop installer proceeds to use free space without warning, if sufficient free space exists, and "install alongside" is selected, then clicking on the forward button just begins the installation without warning. (Bug:766265)

• omap3/omap4 netboot images are known to be too small (Bug:806751).

• The "Memory test" mode is hanging indefinitely without any progress on some systems (confirmed on Dell Mini 10). (Bug:856055)

• Chinese installs need to use the live environment instead of install only, to be able to type localize character. (Bug:871726)

Upgrades

• Ubuntu 11.10 has migrated away from /var/run, /var/lock and /dev/shm and now uses /run, /run/lock and /run/shm instead (respectively). While the Ubuntu AppArmor packages and shipped policy have been adjusted for this, custom policy may need to be updated. The following may be used to aid in migration (it allows both the old and the new paths):

  $ sed -i -e 's#/var/run#/{,var/}run#' -e 's#/var/lock#/{run,var}/lock#' -e 's#/dev/shm/#/{dev,run}/shm/#' <profile>

• amd64 users who updated to oneiric prior to August 16th or who installed oneiric prior to Alpha 3 will need to manually enable multiarch support on their systems to ensure they get the same experience (and see the same packages) as other users. This is as simple as running the following command: $ echo foreign-architecture i386 | sudo tee /etc/dpkg/dpkg.cfg.d/multiarch  An apt-get update later, and you'll have access to the full array of i386 packages in addition to the amd64 ones.

• Any users who have updated to ubuntu 11.10 beta 1 and have not updated since then, may encounter the issue that 'apt-get update' returns non zero, although it does successfully update the Packages file. In GUI tools, this translates to update-manager showing an error, but it does display the updated apt and allow it to be installed. (Bug:871731)

Graphics and Display

• We had to revert from unity-window-decorator to gtk-window-decorator for performance reasons. This means that the "1 px border" for resizing window is back temporarily. (Bug: ???)

• On Intel N10 Graphics, plugging in external monitor to VGA port makes both displays corrupted with thick slanted lines. (Bug:830949)

• Remote Desktop does not work with the -fglrx video driver, nor with the legacy nvidia drivers. You can establish a connection but the remote screen does not update. As a workaround use Unity2d, or switch to the free drivers or nvidia-current. (Bug:772873)

• The Onboard window in Unity2d when maximized puts the window on top of everything and has no window controls when maximised as it refuses focus, and you can't double click the title bar to restore it. Once maximised your only real option is to switch to another workspace using a hard keyboard ctrl+alt+arrow keys then run gconf-editor and in the apps\onboard section change the height, or reboot into Unity3d and double click or drag down the top panel. (Bug:859288).

• Orca can't read what is going on with Unity3d. By default if you install using the screen reader you will boot into the 2d desktop. (Bug: ???)

• For languages that are read left to right (arabic, hebrew), there is some inconsistency in display between the login screen (lightDM) and the desktop environment (unity). (Bug:871764)

Desktop

• The Skype website currently directs users to download a package for 64-bit Ubuntu 11.10 systems which is not compatible with multiarch. Users are instead recommended to install the skype package via the Canonical partner archive using Software Center. Alternatively, you can manually install this i386 package from the command line by running:

 $ sudo apt-get install skype:i386

Kernel

• Sandy Bridge power regression from kernel 3.0.0-6 to 3.0.0-7 (30% more power at idle) (Bug:818830)

Ubuntu Server

• When running an i386 system under a virtual machine without enough memory allocated a kernel error is detected during installation. (Bug:790712)

Ubuntu Cloud

• TODO

Kubuntu

• Kmail migration fails (Bug:857828). You will need to delete your ~/.kde/share/config/kmail-migratorrc file, and run the migrator manually - kmail-migrator --interactive or skip the migration tool and reconfigure Kmail from scratch.

• Shutdown in the live session under VirtualBox sometimes does not work and seems to just hang on the desktop. Just restart the computer with the power button in that case, there is no possibility of data loss. (Bug:805906)

• A window may retain a taskbar entry after closing the application. [https://bugs.kde.org/show_bug.cgi?id=275469 (KDE Bug 275469)]:

Xubuntu

• When using the new plymouth splash screen, occasionally using the desktop cd to install, the message "hit any key to continue" does not appear. Should you get a black screen with text and the sliding throbber, when the throbber stops moving and the cd ejects, remove the cd and hit enter on the keyboard to continue.(Bug:872472)

• There is no screen title or headings when choosing "Install Xubuntu" from the CD menu (Bug:840094)

Edubuntu

• As Edubuntu includes a standard Ubuntu desktop, most of the issues above also apply to Edubuntu

• Advanced package selection doesn't appear in some languages. As a workaround, simply remove the packages you don't want once your system is installed. (Bug:872727)

Ubuntu Core

• DRM libraries are always installed, even for users who are not enabling graphical environments (Bug:819802)

Lubuntu

• In some cases, Lubuntu desktop ISO boot to a terminal prompt instead of the desktop session. You can manually start the session by typing "sudo start lxdm" (Bug:854837)

• Ubiquity require more than 4 Gb of free space to install, please use alternate ISO if you are in this case (Bug:819538)

• Keyboard layout can't be saved using LXKeymap. Please run "sudo dpkg-reconfigure keyboard-configuration" (Bug:729880)

• On persistent mode, items created on the desktop are not displayed until next reboot. (Bug:837470)

日本語版独自の記述

日本語に関する新機能・仕様変更

日本語環境セットアップヘルパはありません

• Ubuntu 10.10までのJapanese Remix環境で提供してきた「日本語環境セットアップヘルパ」は、Ubuntu 11.04以降では提供を行いません。ソフトウェアセンターから必要なソフトウェアの導入を行ってください。

日本語環境に影響する既知の制限・問題点

• Wubiは日本語Remixでは機能しません。

  Ubuntu 11.10では、日本語Remixの作成にLocalized CD Image toolsを用いています。このツールが現時点ではWubiのマスタリングをサポートしていないため、Ubuntu 11.10 Japanese RemixはWubiによるインストールが行えません。
  Wubiを利用してWindows環境にUbuntuを導入したい場合、通常のDesktop CDを用いてください。

日本語入力に関連する制限

• ATOK X3のインストールには「dpkg 1.15.8 対応 deb パッケージ」が必要です

Ubuntu 11.04以降で採用されているdpkg 1.15.8（以降）で行われた仕様変更により、ATOK X3のインストールには「dpkg 1.15.8 対応 deb パッケージ」が必要です。 http://support.justsystems.com/faq/1032/app/servlet/qadoc?QID=048707 から修正版を入手してインストールしてください。

• ATOK X3(iiimf)・ibusがgvim上で正常に動作しない

ATOK X3・ibusは、gvim上では正常に動作しません。gvim上でATOKを利用したい場合、デスクトップ全体で利用するインプットメソッドをximに変更するか、.vimrc（.gvimrc）に以下の設定を追加してください。 

設定：

" IIIMF handling, it must fallbacks to xim (+ set  imactivatekey)
if $GTK_IM_MODULE == "iiim"
  let $GTK_IM_MODULE='xim'
  set imactivatekey=C-space
endif "

" ibus handling, it must fallbacks to xim
if $GTK_IM_MODULE == "ibus"
  let $GTK_IM_MODULE='xim'
endif "

その他のソフトウェアの問題

• UnityのF10キー

「Unity」デスクトップ環境では、［F10］キーはメニューの呼び出しに割り当てられています。本来こうしたメニュー呼び出し操作はインプットメソッドのほうを優先するべきですが（Key Snoop）、現在のUnityではKey Snoopが機能しておらず、インプットメソッドの変換操作中でもメニュー呼び出しが優先されてしまいます。これにより、日本語入力環境の設定によっては、半角英数字への変換といった操作が行えないことがあります。この問題を避けるために［F10］キーによるメニュー呼び出しを無効にしたい場合、端末から'gconftool-2 -s -t string /desktop/gnome/interface/menubar_accel ""' ('は不要) を実行してください。 

• Oneiricの開発版CDでインストールした場合、/var/lib/dbus/machine-idを再生成する必要があります。
