Upgrading Ubuntu 6.10 (Edgy)

As some of you still using Ubuntu 6.10 (“Edgy Eft”) might have noticed, there are no updates for this available anymore. The corresponding package folders are missing on the Ubuntu mirrors and apt/aptitude updates result in a lot of HTTP 404 errors. In case you missed the news, you can still read the End of Life announcement for Edgy.

So, to cut a long story short: you’re still stuck with your legacy Ubuntu version and want to upgrade it. Unfortunately, Update Manager fails because it wants to check the (non-existant) Edgy branch of the Ubuntu apt repository for Edgy updates prior to upgrading to the new version.

The solution (only for the brave ones) is to change the apt sources and perform the update manually.

$ sudo sed -e 's/\sedgy/ feisty/g' -i /etc/apt/sources.list

Following the Feisty upgrade instructions, run these commands:

$ sudo aptitude update && sudo aptitude dist-upgrade && sudo aptitude dist-upgrade
$ sudo aptitude update && sudo aptitude dist-upgrade
$ sudo aptitude -f install
$ sudo dpkg --configure -a

Fix any upcoming errors, so that eventually invoking the sudo aptitude update && sudo aptitude dist-upgrade will show no additional updates to be installed and also displays no errors.

After rebooting to let the kernel update become effective, you should have successfully upgraded to Ubuntu 7.04 (“Feisty Fawn”) which life cycle will end in October 2008. It might be a good idea to consider an upgrade to Ubuntu 7.10 (“Gutsy Gibbon”) or even upgrading to Ubuntu 8.04 LTS1 (“Hardy Heron”) right away.
