I keep trying to upgrade , but am not allowed to, 'cause Debian is saying that someone is using apt, and it can't get a l;ock. I am the only user. What could be holding me up?

Although there might be several package managers e.g. Synaptic, Software Center etc they all use the one and only database. Therefore, you can only use one package manager at a time.

Close everything you can, open a Terminal and try again.

If you are still having problems try running top in a Terminal. What processes are running?
