Please make sure to backup your data before attempting an upgrade.
If you are using Xubuntu 8.04 “Hardy Heron” or newer, you can upgrade your system using the update manager.
- If you are running a Long Term Support release (e.g. 10.04) and want to upgrade to a normal release (e.g. 10.10), then you first need to make sure a new release is listed in the Update Manager. You can do so by opening Applications -> System -> Update Manager -> Settings, then, in the “Updates” tab, set “Show new distribution releases” to “Normal releases”.
- Open Applications->System->Update Manager.
- Click the Check button to check for new updates.
- If there are any updates to install, use the Install Updates button to install them, and press Check again after that is complete.
- A message will appear informing you of the availability of the new release.
- Click the Yes, Upgrade Now button.
- Follow the on-screen instructions.
Install Xubuntu from Ubuntu
If you have an existing Ubuntu, Kubuntu, or Edubuntu installation, it is possible to install Xubuntu and retain your current installation. To do so, just go into Synaptic (or Adept if you use Kubuntu) and install the xubuntu-desktop package. Next time you login, you can choose Xubuntu from the Session menu on the login screen.
If you want to have a default Xubuntu install but have installed Ubuntu or Kubuntu, you can remove all Gnome and KDE packages by following instructions on this page.
Since Xubuntu shares the Ubuntu-base, please reference the Ubuntu wiki for dual boot (installation while keeping another operating system) instructions.
