I upgraded to Alpha 3 today for kicks. sudo do-release-upgrade -d for the bold. I thought I’d share a little hiccup I had in the process.
dpkg: parse error, in file '/var/lib/dpkg/available' near line 54937 package 'virtualbox-2.2':
error in Version string `2.2.4-47978_Ubuntu_jaunty': invalid character in revision number
I just fired up a txt editor, gksudo gedit /var/lib/dpkg/available and took out the virtualbox-2.2 block that was left over from long ago and another virtualbox-3.0 block. Follow that up with a simple sudo apt-get -f install && sudo apt-get dist-upgrade and it’s time to reboot for maverick!
Hope this helped you random googler who finds this.
