I can't install anything right now (or upgrade anything). When I run `sudo apt-get upgrade I get this list of unmet dependencies. At the end it says

E: Unmet dependencies. Try using -f.

When I try sudo apt-get upgrade -f I get

E: Could not perform immediate configuration on 'libc6'. Please see man 5 apt.conf under APT::Immediate-Configure for details. (2)

Nothing happens though. I don't really know what's going on, or how to troubleshoot this. I looked at man 5 apt.conf under Immedate-Configure, but it didn't really tell me anything.

I'm kind of skeptical that all these things need to be installed. I think there's just an error reading some package list or something, so it doesn't know what's installed or not. But I could be wrong about that.

How can I fix these dependency issues?
