Ubuntu 10.04 LTS (Lucid Lynx) Beta 2

(2010.04.08)

Introduction
The Ubuntu developers are moving quickly to bring you the latest and greatest software the Open Source community has to offer. This is the second Ubuntu 10.04 beta release, which brings a host of exciting new features.

Note: This is a beta release. Do not install it on production machines. The final stable version will be released on April 29, 2010.

Upgrading from Ubuntu 9.10 or Ubuntu 8.04 LTS
To upgrade from Ubuntu 9.10 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 '10.04' is available. Click Upgrade and follow the on-screen instructions.

To upgrade from Ubuntu 9.10 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 -d; and follow the on-screen instructions.

To upgrade from Ubuntu 8.04 LTS: follow the same instructions as for the appropriate Ubuntu 9.10 upgrade, but set Prompt=lts instead of Prompt=normal.

New features since Ubuntu 9.10
These features are showcased for your attention. Please test them and report any bugs you find:
http://help.ubuntu.com/community/ReportingBugs

GNOME
Ubuntu 10.04 Beta 2 includes the latest GNOME desktop environment with a number of great new features.

Mozilla Firefox
Default search engine has been changed to Yahoo! The default Home Page will use either Google or Yahoo! depending on user setting.

Linux kernel 2.6.32
Ubuntu 10.04 Beta 2 includes the 2.6.32-16.25 kernel based on 2.6.32.9.

KDE SC 4.4
Kubuntu 10.04 Beta 2 features the new KDE SC 4.4. For more information about new features in Kubuntu, see the Kubuntu technical overview.

HAL removal
This beta sports full removal of HAL from the boot process, making Ubuntu faster to boot and faster to resume from suspend.

Major new version of likewise-open
The likewise-open package, which provides Active Directory authentication and server support for Linux, has been updated to version 5.4. The package supports upgrades from both the officially supported versions 4.0 (Ubuntu 8.04 LTS) and 4.1 (Ubuntu 9.10), as well as the likewise-open5 packages from universe.

Since this upgrade involves a lot of configuration file changes and in-place database upgrades, testing and feedback is appreciated.

New default open source driver for nVidia hardware
The Nouveau video driver is now the default for nVidia hardware. This driver provides kernel mode setting, which will give improved resolution detection. This driver provides hardware accelerated 2D functionality, like the -nv driver it replaces. The nouveau driver is being actively developed upstream and we anticipate this will enable faster bug fixes for problems encountered.

Improved support for nVidia proprietary graphics drivers
Three different NVIDIA proprietary drivers are currently available: nvidia-current (190.53), nvidia-173, and nvidia-96. Thanks to a new alternatives system, it is now possible to install all three of these packages at the same time (although it is only possible to have one configured for use at a time).

Social from the Start
We now feature built-in integration with Twitter, identi.ca, Facebook, and other social networks with the MeMenu in the panel, which is built upon the Gwibber project, which has a completely new, more reliable backend built on top of desktopcouch. Gwibber now also supports a multi-column view for monitoring multiple feeds simultaneously.

New boot experience
Multiple changes to look, feel and speed of the boot experience have been included in the Ubuntu 10.04 LTS beta.

New Indicators
The notification area now features more consistent user experience and design for communication, session management, and many other tasks. See the application indicators page for information on this change.

New Themes
The desktop has been beautified with the addition of two brand new themes, Ambiance and Radiance. New wallpaper and icons are also included.

Ubuntu One File Syncing
Select any folder in your home directory for sync, pick from your existing contacts when sharing folders. An updated preferences application has been added, with more features.

Ubuntu One Music Store
Millions of songs are available for purchase from your Ubuntu desktop, integrated with the Rhythmbox Music Player and using Ubuntu One cloud storage for backup and easy sync. Watch http://one.ubuntu.com/blog for the public beta launch.

New features for Ubuntu Enterprise Cloud (UEC)
The Ubuntu Enterprise Cloud installer has been vastly improved in order to support alternative installation topologies. UEC components are now automatically discovered and registered, including for complex topologies. Finally, UEC is now powered by Eucalyptus 1.6.2 codebase.

Security Issue when upgrading from Lucid Alpha 2
If you installed Lucid prior to Alpha 3, you may have libmysqlclient16 7.0.9-1 installed. This package was present in the Ubuntu archive by mistake and was retracted, but because it has a later version number than the real libmysqlclient16 package, the real package will not be installed automatically on upgrade. To ensure that you have the official package installed on your Lucid system and will receive security support for it throughout Ubuntu 10.04 LTS, it is important that you run sudo apt-get install libmysqlclient16/lucid and follow the instructions.

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 Ubuntu 10.04 Beta 2. 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:

* Because of the new alternatives system used for nvidia driver packages, the nvidia installer from NVIDIA's website currently doesn't work.

* Activating a RAID 1 array in degraded mode is reported to lead to RAID disks being reported as in sync when they are not, resulting in data loss. Since RAID 1 arrays will automatically be brought up in degraded mode when a member disk is unavailable, users with production software RAID 1 disks are advised not to upgrade to the 10.04 LTS Beta until this bug is resolved. (557429)

* When installing with the Kubuntu alternate CD in OEM mode, the "prepare for shipping" icon is absent from the desktop after install. As a workaround, users can use the Kubuntu desktop CD. This issue will be resolved for the 10.04 LTS release. (557309)

* If additional packages are selected for installation in OEM mode, a message will be shown at user configuration time that "An error occurred while installing packages" if no network connection is available. This issue will be resolved for the 10.04 LTS release. (539710)

* LVM, RAID, or encrypted block devices are incorrectly limited to 2TiB. This issue will be resolved for the 10.04 LTS release. (543838)

* The "Reboot now" option in the Wubi installer will sometimes fail to reboot Windows. To work around this issue, you can reboot manually to Ubuntu. (543032)

* Due to a seed issue, Edubuntu doesn't have its artwork in this release. That can easily be fixed post-installation by manually installing the edubuntu-artwork package.
