Introduction
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 5 is the fifth 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.
Upgrading from Ubuntu 9.04
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.
New features in Karmic
Feature development for Karmic is happening with full speed. Please see the Karmic blueprint list for details.
Please test and report any bugs you find:
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 5 includes the latest GNOME 2.27.91 development release.
Empathy has replaced Pidgin as the default instant messaging client, introducing the Telepathy framework.
The gdm 2.27.91 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 UEC
Alpha 5 includes alpha images for the Ubuntu Enterprise Cloud
(UEC) and Amazon's EC2. You can try out the latest Karmic server alpha
instantly on EC2 using a preconfigured AMI, or download an image and
put it into your own cloud with UEC. For information on using Ubuntu
UEC on Amazon EC2, see the EC2 Starter's Guide.
Ubuntu One file sharing
Ubuntu Karmic Alpha 5 ships the Ubuntu One
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 5 includes the 2.6.31-9.29 kernel based on 2.6.31-rc8. 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 5's underlying technology for power management, laptop hotkeys,
and handling of storage devices and cameras maps has moved from "hal"
(which is in the process of being deprecated) to "DeviceKit-power", "DeviceKit-disks" and "udev". When testing Alpha 5, please pay particular attention to regressions in those 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.
iSCSI installation
The iSCSI installation process has been improved, and no longer requires iscsi=true
as a boot parameter; the installer will offer you the option of logging
into iSCSI targets if there are no local disks, or you can select
"Configure iSCSI" in the manual partitioner.
Putting the root filesystem on iSCSI is now supported.

Known issues
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
5. 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:
-
Users
in some timezones will find that their filesystems must be checked
(fsck) immediately after install due to a bug in the installer's clock
handling. Investigation of this issue is ongoing, and we expect it will
be resolved in Alpha 6. (423247)
-
When
using the OEM installation option, the desktop fails to come up after
reboot for some users. Investigation of this issue is ongoing. (403021)
-
The
OEM installer is reported to not correctly set up the end user account
in Alpha 5. Investigation of this issue is ongoing. (423042)
-
Due to a bug in the python-boto package, when running ec2-run-instances to launch an EC2 instance you must pass an additional --user-data x option to the command. This bug will be fixed for Alpha 6. (419306)
-
The virtual
kernel image has been built without virtio drivers, so installing using
the "minimal virtual" option from the Ubuntu Server Alpha 5 will result
in an unusable system after reboot. This problem also affects users of
the linux-image-virtual kernel package who have installed
from earlier alphas. Users are advised to wait until Alpha 6 before
installing or upgrading. (423426)
-
Installation
of an LTSP server using the alternate CD in Alpha 5 will be incomplete
because some recommended packages are not installed. This bug will be
resolved for Alpha 6. As a workaround, users can install the pulseaudio-esound-compat and dhcp3-server packages after installation. (423615)
Reporting bugs
It
should come as no surprise that this alpha release of Karmic Koala
contains other bugs. Your comments, bug reports, patches and
suggestions will help fix bugs and improve future releases. Please report bugs using the tools provided.
