The Ubuntu developers are moving quickly to bring you the absolute latest and greatest software the Open Source Community has to offer. The Karmic Koala Alpha 3 is the third alpha release of Ubuntu 9.10, bringing with it the earliest new features for the next version of Ubuntu.

This is an alpha release. Do not install it on production machines. The final stable version will be released on October 29th, 2009.

To upgrade from Ubuntu 9.04 on a desktop system, press Alt+F2 and type in "update-manager -d" (without the quotes) into the command box. Update Manager should open up and tell you: New distribution release '9.10' is available. Click Upgrade and follow the on-screen instructions.

To upgrade from Ubuntu 9.04 on a server system: install the update-manager-core package if it is not already installed; edit /etc/update-manager/release-upgrades and set Prompt=normal; launch the upgrade tool with the command sudo do-release-upgrade; and follow the on-screen instructions.

Feature development for Karmic is happening with full speed. Please see the Karmic blueprint list for details.

Updated Packages

As with every new release, packages--applications and software of all kinds--are being updated at a rapid pace. Many of these packages come from an automatic sync from Debian's Unstable branch. For a list of all packages being accepted for 9.10 Karmic Koala, please subscribe to karmic-changes:

GNOME

Ubuntu Karmic Alpha 3 includes the latest GNOME 2.27.4 development release.

Empathy has replaced Pidgin as the default instant messaging client, introducing the Telepathy framework.

The gdm 2.27.4 login manager is a complete rewrite compared to the version in earlier Ubuntu releases.

Kubuntu

Kubuntu includes its first Netbook release, Social from the Start and the latest KDE packages. See the Kubuntu technical overview

Ubuntu One file sharing

Ubuntu Karmic Alpha 3 ships the https://ubuntuone.com/ file sharing service by default, providing tightly integrated file synchronization of your computer with other computers and the Ubuntu One network storage service.

Linux kernel 2.6.31

Alpha 3 includes the 2.6.31-3.19 kernel based on 2.6.31-rc3. The kernel ships with Kernel Mode Setting enabled for Intel graphics (see below). linux-restricted-modules is deprecated in favour of DKMS packages.

hal deprecation

Karmic Alpha 3's underlying technology for power management, laptop Hotkeys, and handling storage devices and cameras maps was moved from "hal" (which is going to be deprecated soon) to "DeviceKit-power", "DeviceKit-disks" and "udev". When testing Alpha 3, please pay particular attention to regressions in those two areas and report bugs.

New Intel video driver architecture available for testing

The Intel video driver has switched from the "EXA" acceleration method to the new "UXA". This solves major performance problems of Ubuntu 9.04, but could use further testing to flag any regressions it may bring.

Feedback about the new "kernel mode setting" feature is also heavily appreciated. This will reduce video mode switching flicker at booting, and dramatically speed up suspend/resume. Please see the instructions and feedback page for details.

New default compiler

Karmic uses GCC-4.4 as the default compiler, which in some parts is more strict than GCC-4.3, see list of changes. Please make sure to test packages on karmic or in a karmic chroot before upload.

ext4 by default

The new "ext4" filesystem is used by default for new installations of Karmic; of course, other filesystems are still available via the manual partitioner. Existing filesystems will not be upgraded.

If you have full backups and are confident, you can upgrade an existing ext3 filesystem to ext4 by following directions in the Ext4 Howto (note that the comments on that page at the time of writing about Ubuntu's use of vol_id vs. blkid are out of date and are not applicable to Karmic). Maximum performance will typically only be achieved on new filesystems, not on filesystems that have been upgraded from ext3.

GRUB 2 by default

GRUB 2 is the default boot loader for new installations of Karmic, replacing the previous GRUB "Legacy" boot loader. Existing systems will not be upgraded to GRUB 2 at this time, as automatically reinstalling the boot loader is an inherently risky operation.

If you wish to upgrade your system to GRUB 2, then see the GRUB 2 testing page for instructions. See also the upstream draft manual.

Some features are still missing relative to GRUB Legacy. Notable among these are lock/password support, an equivalent of grub-reboot, and Xen handling.

As is to be expected at this stage of the release process, there are several known bugs that users are likely to run into with Karmic Alpha 3. We have documented them here for your convenience along with any known workarounds, so that you don't need to spend time reporting these bugs again:

• The GNOME login manager (gdm) does not yet have a graphical configuration tool. (395299)

• If you install Karmic Alpha 3 alongside Windows, the grub boot menu may not offer to start Windows. (402795)

• If you have internal hard disk partitions aside from Ubuntu itself, GNOME will attempt to automatically mount them at startup and ask for your password. Just cancel the dialog, unless you actually want to work with them. (396448)

• The GNOME desktop displays two mixer applets on the amd64 desktop CD and alternate installs. It is already fixed in the i386 desktop images, and will be fixed if you upgrade your system after installing. (401294)

• Building LTSP client chroots currently fails. (383177)

• The likewise-open5 package is currently non-functional because of an incompatibility with MIT Kerberos 1.7. The likewise-open package (version 4) continues to be usable, and likewise-open5 will be fixed in the near future. (385475)

• The Ubuntu Netbook Launcher crashes on shutdown. (395468)

• The Kubuntu Netbook Edition is missing the "install" icon on the desktop. You can start the installation from the menu. (402878)

• The Kubuntu Netbook Edition image does not install under Windows (with wubi). (402850)
