Clean up Xubuntu hardy without reinstalling?
 

Just wondering because some package update messed up a program.. Cant figure out which update it was, so I was wondering if there is any way to clean it up to being basically a clean install without actually reinstalling it?

if you installed from a disk, you should be able to boot from the disk, which would give you the option to "repair your system"

umm...this probably won't help much, but you can get rid of recent or old installation files with

sudo apt-get clean (recent)
and
sudo apt-get autoclean (old)

oh and if you do ever figure out which package it was...or want to guess or whatever...you can do
sudo apt-get remove [whatever the package was]
or even
sudo apt-get purge [what the package was]
