Ubuntu 12.10 ´Quantal Quetzal´ Alpha 3
Note di rilascio:

The Ubuntu developers are moving quickly to bring you the absolute latest and greatest software the Open Source community has to offer. The Quantal Quetzal Alpha 3 Release of Ubuntu 12.10 is a developer snapshot to give you a very early glance at the next version of Ubuntu.

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.

Linux kernel 3.5

Quantal Alpha-3 includes the 3.5.0-6.6 Ubuntu kernel which was based on the v3.5 upstream Linux kernel. This is an update from the 3.5.0-2.2 Ubuntu kernel which shipped in the Quantal Alpha-2 release and was based on the v3.5-rc4 upstream Linux kernel. Other notable changes with the Quantal Alpha-3 kernel include changing the default scheduler back to Deadline for both the server and desktop, homogenization of the kernel configs for supported flavors and arch´s, removal of redundant firmware files, and misc bug fixes. As with the Quantal Alpha-1 and Alpha-2 releases, the Quantal Alpha-3 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 3.0

For 12.10, we intend to ship only Python 3 with the Ubuntu desktop image, not Python 2. Alpha-3 continues this process.

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.


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 1.12, mesa 8.0.3, 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. We anticipate doing another X.org stack update later on in the Quantal development cycle.

The first unity 6 version landed with some bugs fixed and refactoring for the features that will land next.

Other notable updates include:

- Jockey has been deprecated in favor of a "Drivers" component in software-properties.
- Libreoffice got updated to 3.6.0rc2.
- GNOME has been updated to 3.5.4 for most of the components.

Ubuntu Server

We are continuing to trial the removal of i386 Ubuntu Server CD image. This means that the primary supported installation method is AMD64, the 64-bit release (X86_64). However, other supported installations mechanisms for i386, such as mini.iso and netboot are still supported, which are an initial minimal download; and install directly from the network. i386 images for Alpha are available, but not declared as part of the Alpha 3 release. Feedback is most appreciated, if this causes issues for particular hardware.

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.
Juju Charm maintainer assignment.
Facter integration with Juju done.
Tomcat 7 replaces Tomcat 6 in Ubuntu main (and on the Server ISO)
MAAS IPMI support added
Ceph updated to 0.48 (argonaut stable release)
OpenStack Folsom testing packages available.
Openstack instance architecture detection support added, and heterogeneous scheduler for ARM done.
Spec to improve reliability of apt through hash defined. Feedback welcomed.
armhf cloud images available.
