How to get temp-crap out off Ubuntu to save diskspace

Well I am actually still pretty new to Linux in general, but I got pretty much a hang off it already, but now I wanted to know how I can throw out unneeded rubbishfiles out UbuntuLinux to save some MB's on my 10GB rootpartition.

Uninstall all the packages you don't need? If it's a fresh install, then there is nothing else taking up any mentionable space.

Do "sudo apt-get clean" to get rid of old .deb files that are no longer needed.

Other temporary files are automatically cleared so you don't need to worry much about them.
