Cleaning up after upgrades?

[gabello]

Hi, I'm just upgrading from 8.04 to 9.04 using the Distribution Upgrade option (thus installing 8.10 also). Since I'm quite limited in HDD space allocated to Ubuntu (I installed it first using wubi and I'm on a dual boot machine) I want to know what cleaning procedures I need to do after I install 8.10 (or 9.04) in order to remove all the unused installations files.

Thank you

"sudo apt-get clean". This will remove all apt's cached package files. That's pretty much all you need to do. :)
