  • Click Upgrade and follow the on-screen instructions.

To upgrade from Ubuntu 12.04 LTS on a server system:

  • Ensure that /etc/update-manager/release-upgrades includes Prompt=Normal.

  • Install the update-manager-core package if it is not already installed.

  • Launch the upgrade tool with the command sudo do-release-upgrade -d.

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: .

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.


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.


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 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

  • Addition of 'More Suggestions' category which delivers commercial content to the Dash via the 'Unity Shopping Lens'
  • Numerous fixes and refinements to the dash
  • Support addition of webapps in the launcher by default (including Amazon & Ubuntu One Music stores)

  • An updated indicator-messages including a new libmessaging-menu api (deprecating the old libindicate library)
  • All launcher icons (except the BFB and Trash) should now be movable
  • Added the ability to unlock removable-storage icons from the launcher to de-clutter it
  • When in spread mode (Super+W) it's possible to close windows by clicking the close button revealed when hovering over them
  • Gwibber lens now features preview support in the dash
  • Webapps can now trigger package downloads where required by compliant websites visited by the user
  • Additional icons have been added to the filesystem lens to enable dragging and dropping filesystems (such as USB sticks) into the launcher
  • Previews in the video lens now show details for remote Amazon videos
  • Unity and unity-panel have been ported to atk-bridge for accessibility

Other notable updates include:

  • Jockey has been deprecated in favor of a "Drivers" component in software-properties.
  • Libreoffice was updated to 3.6.1 with built-in menubar & HUD support without needing a separate plugin.

  • GNOME has been updated to 3.5.92 for most components (some to 3.6.0)
  • Accessibility is turned on by default.

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:

  • Juju Charm Store policy implementation, and Charm maintainer assignment and Charm Quality Ratings implemented.

  • Ceph updated to 0.48.1 (upstream argonaut stable release):
    • RADOS Gateway (S3 and Swift Compatible) now available.
    • Performance improvements on x86 architectures through use of gperftools.
  • Floodlight (Openflow Network Controller) and mininet (Network Simulation) packages available.
  • OpenStack Folsom testing packages available.

  • Openstack instance architecture detection support added, and heterogeneous scheduler for ARM done.
  • armhf cloud images are available.
  • cloud-init support for "config drive v2" from Openstack Folsom.
  • Ubuntu now has native packaging for Amazon AWS RDS (rdscli), Identity Management (iamcli), Elastic LoadBalancing (elbcli), ElastiCache (elasticache), and CloudWatch (moncli) in the Multiverse and Universe archive areas. Additionally newer versions of EC2 API (ec2-api-tools) and AMI (ec2-ami-tools) are avialable.

  • now has Quick Start buttons to enable Quick Start like function for Amazon AWS images.

  • Cloud Images no longer have a five second boot time out. Additionally, the "record_fail" time out -- where a failed boot would result in a hung Grub console -- has been eliminated. This specifically affects KVM, Amazon AWS HVM images, and Windows Azure Images.
  • Starting with Ubuntu 12.10, the Ubuntu Cloud Images no longer have the 'ubuntu' user pre-populated in the images. The 'ubuntu' user is now created on first boot by cloud-init unless instructed otherwise. This allows easy creation of instances with no 'ubuntu' user and even no users.
  • Ubuntu 12.10 provides Apache Tomcat 7 as the default, supported version of Tomcat. Existing installations of tomcat6 will continue to function; its recommended that users upgrade to the tomcat7 package as soon as possible.
  • New version of MAAS is available. This realease has dropped the usage of maas-provision, and features its own, MAAS managed, DNS and DHCP server.
  • Due to a binary naming issue between the node and nodejs packages, nodejs now ships with its binary installed to /usr/bin/nodejs. Users of nodejs applications sourced from outside of the Ubuntu distribution should either use the nodejs-legacy package (which continues to provide /usr/bin/node) or migrate their applications to use the /usr/bin/nodejs interpreter.


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:

  • KDE Plasma and Applications 4.9 add many new features and fixes
  • Calligra's Krita adds a world class painting application while Kexi is a full featured database app
  • New login manager LightDM adds a guest session feature for letting your friends use your computer quickly
  • Telepathy-KDE becomes the default chat program offering easier set up to modern networks like Facebook and GTalk
  • New applications on the images include Skanlite for scanning, Kamoso for webcam images, tablet config, GTK config and Print Manager
  • Digikam 2.8 adds better photo handling

  • The release of Rekonq 1 gives Kubuntu the stable web browser it deserves.
  • A Facebook resources in Kontact means you can get calendar and contact information from your Facebook account.
  • While a Google resource means you can get calendar information from your Google account .
  • OwnCloud 4 gives many web applications in your own remote or local cloud
