In this article we'll see how to upgrade Xubuntu 12.04 to Xubuntu 12.10, using both a graphical method and a command line method.
But first there's a few thing to bear in mind:
- Backup your files.
- Xubuntu 12.04 is LTS (Long Term Supported) so it might be more stable than subsequent releases.
- The upgrade might take some time, so be patient.
- If you added PPAs manually they'll be disabled. If they support 12.10 you can add them again later.
Upgrade from Update Manager
Open "Update Manager" (Applications Menu > System > Update Manager). Then proceed as described here. Essentially all you have to do is change the update settings so that you'll be notified when there's a newer version available, reopen "Update Manager" and click the "Upgrade" button next to the message that is saying that a new Xubuntu version is available.
Upgrade from terminal
Open a terminal window and run the command below. Then follow the instructions presented by the command.
sudo sed -i 's/prompt=lts/prompt=normal/g' /etc/update-manager/release-upgrades && sudo do-release-upgrade
