- 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.

- 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:

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.
