I did had a post about how to upgrade a Ubuntu Server version. Anyway i repeat it again, iIf you have ubuntu 10.10 Lucid Lynx or older version of ubuntu installed and you want to upgrade to Ubuntu 10.10 Maverick Meerkat, you can do it by following these instructions:
1. Press Alt+F2.
2. Type in update-manager -d into the command box.
3. Check for updates, then Install them.
4. Finally click Upgrade to the New Ubuntu release 10.10.

4. It is also possible to use do-release-upgrade to upgrade to a development version of Ubuntu. To accomplish this use the -d switch:
$ do-release-upgrade -d
(then follow the on-screen instructions.)
