APT Problems

[Bill Hartwell]

I'm not sure what's going on here, since I have installed all the keys 
for the repositories and have the latest version of GPG installed and 
running.

When I try to install ANY package, I get to the signature verification 
stage, and it fails. It doesn't matter if it's from the CD, from the 
main repository, or even a package I've saved on my HD and am trying 
to install directly. I can not install anything without 
using 'dpkg -i --force-bad-verify <package name>'

Any suggestions for how to fix this?
