Ask Ubuntu is a question and answer site for Ubuntu users and developers. It's 100% free.

I ask because Ubuntu Tweak's Janitor is frozen due to the sheer number of packages in the cache that accumulated during the upgrade from 12.10 to 13.04.

sudo apt-get clean will do what you want, though it does seem odd that it would freeze based on the amount of packages in the cache.

OP has been having quite a few other issues as well.. –  user25656 Apr 26 '13 at 4:37
Just happened to me on 14.04. Ubuntu Tweaks frozen on package 2236... oh well. Nice thing having askubuntu around. –  Rmano May 21 at 15:54

While I could use the terminal to perform this, I'd prefer the GUI.

In Synaptic Install synaptic, go to SettingsPreferencesFile tab. Choose only delete packages that are no longer available and you're done.

You can also use Ubuntu Tweak, but it takes much longer to do the job.
