I tried following the instructions described here: https://help.ubuntu.com/community/EOLUpgrades/Jaunty

However, this gives me the following error:

root@hawk:~# do-release-upgrade 
Checking for a new ubuntu release
Done Upgrade tool signature
Done Upgrade tool
Done downloading            
extracting 'lucid.tar.gz'

tar: Removing leading `/' from member names

Reading cache

Checking package manager

Can not upgrade 

An upgrade from 'jaunty' to 'lucid' is not supported with this tool. 


How can I do this safely?

  • And you really did a sudo aptitude update && sudo aptitude safe-upgrade before? – mailq Jul 17 '11 at 15:46

I always did it through changing the repositories : Don't forget the -i below.

   sed -i 's/jaunty/lucid/g' /etc/apt/sources.list

    aptitude update
    aptitude upgrade
    aptitude dist-upgrade
