I wanted to outline instructions on how to upgrade from Ubuntu 7.04 to Ubuntu 7.10. The upgrade steps try to be very user friendly and can be done without any manual “command line trickery”. Upgrading using these methods are only supported for machines currently running Ubuntu 7.04.
Preparing for the Upgrade - Gnome Desktop
Before you attempt to upgrade from 7.04 to 7.10 you need to make sure that your current installation is completely up to date. This will help avoid conflicts or missed packages during the upgrade process.
