Upgrading from Ubuntu 12.04 LTS

To upgrade from Ubuntu 12.04 LTS on a desktop system:

To upgrade from Ubuntu 12.04 LTS on a server system:

Note that the server upgrade will utilize GNU screen and automatically re-attach in case of e.g. dropped connection problems.

Offline upgrade options via alternate CDs are no longer offered for Ubuntu Desktop and Ubuntu Server. Please ensure you have network connectivity to one of the official mirrors or to a locally accessible mirror and follow the instructions above.

Download the Beta 2

Beta 2 images can be downloaded from a location near you.
Note: The Ubuntu Desktop images are now bigger than a standard CD, and you should use a USB or DVD for installation. Some image consolidation has occurred as well.

You can download Beta 2 ISOs from:

New features in Quantal

Please see the Quantal 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 Debian's unstable branch; others have been explicitly pulled in for 12.10 Quantal Quetzal.

For a list of all packages being accepted for 12.10 Quantal Quetzal, please subscribe to quantal-changes: https://lists.ubuntu.com/mailman/listinfo/quantal-changes .

Linux kernel 3.5.4

Quantal Beta-2 includes the 3.5.0-15.23 Ubuntu Linux kernel which was based on the v3.5.4 upstream Linux kernel. This is an update from the 3.5.0-13.14 Ubuntu kernel which shipped in the Quantal Beta-1 release and was based on the v3.5.3 upstream Linux kernel. Key changes with the Quantal Beta-2 kernel includes upstream bug fixes for audio and eCryptfs, an updated and re-enabled AUFS, mei driver udpates, additional support for Hawsell graphics, and misc config changes and bug fixes. As with the Quantal Alpha and Beta-1 releases, the Ubuntu kernel continues to include the transitioning of the i386 generic-pae flavor to become the generic flavor offering, collapsing of the virtual flavor back into the generic flavor, and standardizing of the entire linux-meta package.

Python 3.2

We eventually intend to ship only Python 3 with the Ubuntu desktop image, not Python 2. Beta-2 continues this process, although we will not be able to convert everything to Python 3 for Ubuntu 12.10.

If you have your own programs based on Python 2, fear not! Python 2 will continue to be available (as the python package) for the foreseeable future. However, to best support future versions of Ubuntu you should consider porting your code to Python 3. Python/3 has some advice and resources on this.

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 checks for duplicates on the client side, which will avoid uploading debug data and creating Launchpad bug reports unnecessarily in many cases now.

Ubuntu

There is no longer a traditional CD-sized image, DVD or alternate image, but rather a single 800MB Ubuntu image that can be used from USB or DVD. Users who previously installed using LVM or full-disk encryption via the alternate CD will find that these installation targets are supported by the consolidated image in 12.10.

Update Manager has been streamlined and renamed Software Updater. It also now checks for updates when launched.

A new X.org stack has been introduced which includes xserver 1.13 candidate versions, mesa 9.0, and updated X libs and drivers. The new xserver provides improved multiseat support, better smooth scrolling, and a large variety of bug fixes. The proprietary -nvidia driver now supports the RANDR standard for monitor configuration.

Compiz with GLES support landed, making unity-3d work again on the pandaboard.

Unity was updated to version 6.6 including support for

Other notable updates include:

Ubuntu Server

Unlike the Desktop flavour, we are currently targeting the 12.10 Server image to fit onto a standard cd image (703MB).

Notable updates:

Kubuntu

Kubuntu now comes on 1GB images for a USB drive or DVD. The addition of encrypted and LVM partitioning options means we no longer are including alternate text installer images with this release.

Other notable updates:

More information can be found at: https://wiki.kubuntu.org/QuantalQuetzal/Beta2/Kubuntu

Xubuntu

Xubuntu fits a standard CD image for Beta 2 and targets to fit one for the final release. There is no alternate images or Wubi support for Xubuntu 12.10.

New features in Xubuntu Beta 2 include:

Edubuntu

Lubuntu

Notable updates include:

Ubuntu Studio

Notable updates for 12.10 include:
