Upgrading from a previous release

Upgrading is not recommended because of various bugs. One of those bugs is 1284635. But, if you still prefer to perform an upgrade, follow these instructions:

To upgrade from Ubuntu Studio 13.10 using GUI tools:

  • Open Software Sources.
  • 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 '14.04 LTS' is available.
  • Click Upgrade and follow the on-screen instructions.

To upgrade from Ubuntu Studio 13.10 using CLI tools:

  • 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.


Feature Changes for 14.04 LTS

  • New installer ubiquity plugin which allows you to select packages to install from our workflow metas, audio, video, graphics, photography and publishing.
  • linux-lowlatency is now merged with linux-generic master branch, which means the two are almost identical feature wise. linux-lowlatency continues to be configured for preemtiveness and irq threading and depends on the rtirq script.
  • EFI support
  • gtk3 indicator support in the panel
  • IBus was dropped (1284635)

  • Speech-dispatcher and espeak were added, in addition to Orca and brltty, to further improve accessibility with braille and speech support during installation.

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 14.04 LTS.

Known issues

  • Wrong default kb layout in login screen after installation.
  • Wrong default language in session after installation (1308936)

  • usb2/usb3 audio devices may perform badly (1308628)

  • Xfce4 Power Manager does not restore screen power (1259339). You can try running xrandr, which has worked as a problem-free workaround for some users. Alternatively, to restore a working desktop go to TTY1 (Ctrl+Alt+F1) and restart lightdm with sudo service lightdm restart. NOTE: You will lose all unsaved work in progress! It appears that all instances of this bug so far are caused by suspending by closing the laptop lid - suspending from the logout dialog works to the best of our knowledge.

  • Window manager shortcut keys don't work after reboot (1292290)

  • IBus is dropped from the default installation due to a high-influencing bug (1284635); the team looks to get this bug fixed soon and to reintroduce IBus in a future point release. If you are upgrading to 14.04 from a current version in which IBus is still installed but unused - you will need to either set-up IBus for your keyboard layout after rebooting or purge it. Alternatively purge IBus before upgrading.
