Press Alt + F2 and run the following command:
update-manager -c
You should see a window similar to this:
Click on the 'Upgrade' button and start the upgrading process.
The update-manager
manpage states that the parameter is for:
-c, --check-dist-upgrades
Check if a new distribution release is available
Start Update Manager and check that you have it set to display new versions of Ubuntu. Click 'Settings' and select 'For any new version' like shown below.
