Every time I open synaptic, update manager, software center, or ubuntu tweak (basically any package manager).. the app will pop up for a split second then close. I have tried restarting but I get the same problem.

Figured it out via this forum post.

All I had to run was sudo rm -rf /var/cache/apt/*.bin in the Terminal.

Thanks to Joril for helping me figure out what to look for.

This works. I have no idea why the other answer has an up vote. – nbolton Apr 28 '11 at 12:06
I upvote'd it because it actually did provide me with enough information to google and figure out the answer. =) – RyanScottLewis Apr 29 '11 at 10:59

You should try starting the application from the command line and see if there's an error message, e.g.

sudo synaptic
