Everything has been running fine for the past couple months, but now I'm having problems with apt-get. I last updated about a month ago and now whenever I try and update, there are no new updates, which is a little strange. I've installed Tor and didn't know if that would interfere with apt-get.

You're running Squeeze, which has finally transitioned to be the stable release. As a result, it doesn't get updates anymore until a new release comes out. 6.0.1 should be out in a week or two, so I expect the stable repositories to have updates then.

In the meantime, put these into /etc/apt/sources.list

deb     http://security.debian.org/ squeeze/updates main contrib non-free
deb     http://ftp.us.debian.org/debian squeeze-updates main

That way, you'll get important security updates and other important updates that can't wait for an incremental release. Change the URLs to be your preferred mirror.

Thanks! That worked perfectly!
