= Introduction =

The Ubuntu developers are moving quickly to bring you the absolute latest and greatest software the Open Source community has to offer. The Precise Pangolin Alpha 1 Release of Ubuntu 12.04 is a '''developer snapshot''' to give you a very early glance at the next version of Ubuntu.

= Get Ubuntu 12.04 =
== Upgrading from Ubuntu 11.10 ==

To upgrade from Ubuntu 11.10 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 '12.04' is available. Click Upgrade and follow the on-screen instructions.

To upgrade from Ubuntu 11.10 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 1 ==

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.

You can download Alpha 1 ISOs from:

= New features in Oneiric =

Please see the [[https://blueprints.launchpad.net/ubuntu/precise/+specs|Precise 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 came from an automatic sync from [[http://www.debian.org|Debian's]] Unstable branch, others have been explicitly pulled in for 12.04 Precise Pangolin.

For a list of all packages being accepted for 12.04 Precise Pangolin, please subscribe to precise-changes: https://lists.ubuntu.com/mailman/listinfo/precise-changes

Some of the key packages making their first appearance with this Alpha 1 release are:
 * [[http://kernel.org|Linux]] Kernel 3.2-rc3
 * ?

=== Linux kernel 3.2 ===

Alpha 1 includes the 3.2-rc3 kernel which is based on the latest mainline release candidate kernel at kernel milestone freeze [[http://kernel.org|kernel]]. This is an update from the v3.0 kernel in Oneiric.

== General ==

Until Ubuntu 11.10, the Unix group for administrators with `root` privileges through sudo had been `admin`. Starting with Ubuntu 12.04 LTS, it is now `sudo`, for compatibility with Debian and sudo itself. However, for backwards compatibility, `admin` group members are still recognized as administrators.

Automatic Apport crash reporting has been enabled by default again to catch problems early on. It now [[http://www.piware.de/2011/11/apport-1-90-client-side-duplicate-checking/|checks for duplicates on the client side]], which will avoid uploading debug data and creating Launchpad bug reports unnecessarily in many cases now.

== Ubuntu ==

The default music player has been [[UbuntuSpec:desktop-p-default-apps|switched to Rhythmbox]]. There is no UbuntuOne Music Store yet, this still needs to be ported to GTK 3.
