Clear message

We’re preparing to release Kubuntu 11.10, the Oneiric Ocelot, in October 2011. With this beta pre-release, you can see where we’re at with our bug fixing and polishing of the official release. Read on for some feature highlights. For more information, check out the Oneiric Ocelot status page, to get a better understanding on what we’re planning.

NOTE: This is an beta pre-release. Kubuntu Pre-releases are NOT reccomended for:

  • Regular users who are not aware of pre-release issues
  • Anyone who needs a stable system
  • Anyone uncomfortable running a possibly frequently broken system.
  • Anyone in a production environment with data or workflows that need to be reliable.

Kubuntu Pre-releases ARE recommended for:

  • Regular users who want to help us test by finding, reporting, and/or fixing bugs.
  • Kubuntu developers

Getting Kubuntu 11.10 Beta 2

Upgrading from Previous Versions

To upgrade to Kubuntu 11.10 from an older release, follow the Upgrade Instructions.

Download a Disk Image

Instructions for burning the image to a CD/DVD or USB flash drive can be found on the Burning ISO Howto.

We recommend you learn how to check your CD image so your pre-release is as it’s supposed to be. Compare your MD5 checksum with the correct ones found alongside the CD images.

Beta 2 Highlights

Plasma and KDE Applications 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 here and here.



Along with KDE 4.7, 11.10 also introduces the new KDEPIM suite, which includes the new Kmail 2. The look and feel is familiar, but under the hood, most of the PIM suite is now fully migrated to the Akonadi storage service.

IMPORTANT: Do note that this is a major upgrade to the mail, calendar and addressbook systems, and as such 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 test upgrading to 11.10.

Amarok 2.4.3


This new and improved version of the default music player features native support for remote NFS & 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 2.4.1 and 2.4.3

Muon Suite


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.


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.

KWin OpenGL ES

The new package kde-window-manager-gles allows testing of the Plasma Workspace's window manager using OpenGL ES instead of regular OpenGL. This new technology is particular interesting in the not so distant future for mobile devices. For more information read up on Martin Gräßlin's blog.

Known Problems

  • 838325 kubuntu-full doesn't install complete system - If installing from the Kubuntu DVD, a fully functional system isn't installed. To work around this for Oneiric Beta 1, use the text mode installer and select both the kubuntu-desktop and kubuntu-full tasks.

  • 805906 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.

  • KDE Bug 275469 A window may retain a taskbar entry after closing the application.
