Feistier than ever

Upgraded today to Kubuntu 7.04 Feisty Fawn.
The upgrade took a whole night but it worked without a single glitch. Wow! :-O
Somehow I managed to empty 2 Gigs on my hard drive because I read on the internet that upgrade needs approximately 1.3 Gigs of space. Well it's true. After the upgrade I was left with ~500 MB of free space. After I checked that everything works and nothing was broken during the upgrade I wished I could clean Edgy Eft's remains. I opened a Konsole window and entered:
sudo apt-get clean
and to be sure:
sudo apt-get autoclean
and then I checked how much space was left on a hard drive.
The result: 2 Gigs.
Bling! :-)
