Upgrading from Ubuntu 14.04 LTS

To upgrade on a desktop system:

  • Press Alt+F2 and type in "update-manager" (without the quotes) into the command box.
  • Update Manager should open up and tell you: New distribution release '14.10' is available.
  • Click Upgrade and follow the on-screen instructions.

To upgrade 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.

  • Follow the on-screen instructions.

Note that the server upgrade will use GNU screen and automatically re-attach in case of 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.


New features in 14.10

Please see the Utopic 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 Ubuntu 14.10.

For a list of all packages being accepted for Ubuntu 14.10, please subscribe to utopic-changes.

Linux kernel 3.16

AppArmor

AppArmor added support for fine-grained mediation of unix(7) abstract and anonymous sockets and also added various policy updates and bug fixes. AppArmor policy has been adjusted for packages that ship it to work with these changes, but local policy may need to be adjusted unix rules. See man 5 apparmor.d for details.

Oxide

Oxide has been updated to use the latest Chromium Content API and includes numerous bug fixes and features to better support webbrowser-app, webapps and apps using UbuntuWebViews. Oxide is a webview based on Chromium to deliver web content. Oxide allows us to better support 3rd party developers and applications within the Ubuntu archive by providing a fast, secure and up to date webengine library for the duration of this release. While other web content libraries such as those based on webkit are available, their maintenance will be limited to new upstream minor version releases only, and application developers are encouraged to use Oxide instead.

Known issues

As is to be expected, at this stage of the release process, there are some significant known bugs that users may run into with this release of Ubuntu 14.10. The ones we know about at this point (and some of the workarounds), are documented here so you don't need to spend time reporting these bugs again:

Boot, installation and post-install

The 32-bit powerpc kernel flavour (powerpc-smp) shipped with beta-2 fails to boot. This is resolved in the subsequent kernel being pushed out the day after the beta.

Due to a grub bug, the ppc64el image fail to boot, and were thus not released. This will be fixed before release.

Upgrade

Power Management

Desktop

Under certain circumstances (so far only reproducible in certain VM environments), lightdm will fail to start on boot. It can be manually started from a console with "sudo service lightdm start". This will be resolved shortly after beta-2 is out.

Migration

Graphics and Display

Networking

Kernel

For a listing of more known issues, please refer to the Utopic Unicorn bug tracker in Launchpad.
