Ubuntu 11.10 Alpha 2 Released

Posted by : Rahmat Ade Saputra
The Ubuntu developers are moving quickly to bring you the absolute latest and greatest software the Open Source community has to offer. The Oneiric Ocelot Alpha 2 Release of Ubuntu 11.10 is a developer snapshot to give you an early glance at the next version of Ubuntu.
One of the requests received during the last Ubuntu Developer Summit was to provide a bit more information about the release process, and what's happening there. With this in mind, the release team will be adding a section about "what's happening in the background", to each of the milestones for those who are interested as part of this Technical Overview.


Upgrading from Ubuntu 11.04

To upgrade from Ubuntu 11.04 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 '11.10' is available. Click Upgrade and follow the on-screen instructions.
To upgrade from Ubuntu 11.04 on a server system: install the update-manager-core package if it is not already installed; launch the upgrade tool with the command sudo do-release-upgrade -d; and 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 e.g. dropped connection problems.

Download the Alpha 2

This release is for developers only. Most of these images are oversize; you can use either a DVD or USB for installation instead of a CD.

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 came from an automatic sync from Debian's Unstable branch, others have been explicitly pulled in for 11.10 Oneiric Ocelot.
For a list of all packages being accepted for 11.10 Oneiric Ocelot, please subscribe to oneiric-changes: https://lists.ubuntu.com/mailman/listinfo/oneiric-changes
Some of the key packages making their first appearance with this Alpha 2 release are:

GNOME 3 updates

Alpha-2 ships GNOME 3.0, with some parts already upgraded to the 3.1.2 alpha releases.
Unity, the theme, and Ayatana scrollbars were updated for GTK/GNOME 3.

Email

The standard email client is now Mozilla Thunderbird. GNOME Evolution continues to be supported, but is not on the CD images. (desktop-o-default-email-client)

Backup

The Déjà Dup backup system is now included in the standard installation, providing simple and secure user data backup over the network. You can set it up in the "Backup" category in the control center. (desktop-o-deja-dup-default)

Login manager

lightdm replaced gdm as the login manager. Please note that the theme is only preliminary; please do not report bugs about missing icons, or the bad visual design. (desktop-o-lightdm)

Default file permissions

The default umask for users who have a private user group (e. g. the primary group of user "joe" is group "joe") was changed from 022 to 002. This means that files created by user "joe" are now group writable by default, which makes it a lot easier to share data between trusted users by putting other users into the private user group. (umask-to-0002)
