Upgrading from Ubuntu 16.10

To upgrade on a desktop system:

  • Open the "Software & Updates" Setting in System Settings.

  • Select the 3rd Tab called "Updates".
  • Set the "Notify me of a new Ubuntu version" dropdown menu to "For any new version".
  • Press Alt+F2 and type in "update-manager -d" (without the quotes) into the command box.
  • Update Manager should open up and tell you: New distribution release '17.04' is available.
    • If not you can also use "/usr/lib/ubuntu-release-upgrader/check-new-release-gtk"
  • 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.

  • Make sure the Prompt line in /etc/update-manager/release-upgrades is set to normal.

  • 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.

There are no offline upgrade options 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.

Known issues

As is to be expected, with any release, there are some significant known bugs that users may run into with this release of Ubuntu 17.04. 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:

OpenVPN

OpenVPN 2.4 removed its tls-remote option. Current setups using that option will fail to work. Update your configuration to use verify-x509-name instead.

Desktop

  • GTK+ 3.20 requires theme developers to make changes to their themes. Many (but not all) popular themes are now compatible with GTK+ 3.20.
  • Unity 8 session sometimes locks up when you press Print Screen (1525285)

  • Unity 8 session locks up when you press media meta keys such as play/pause. (1633046)
