It is probably the case that packages that are depended on are not yet
available in the repository. If this goes away within a day or two this
is in general nothing to be worried about.

You could run "sudo aptitude update && sudo aptitude upgrade" in a
terminal. It will give more information about why the upgrade can't be
performed. Try and report the info in a reply, then we'll see further.

You do not have the signature keys for these third-party repositories.
They are needed to verify the integrity of the packages. They can be
added in the authentication tab in menu System > Administration >
Software Sources or from the command line. OFten, third-party
repositories have a key and instructions, often they don't. Then you
need to trust that nobody who has no authority has changed the software
to include malicious code.

This repository does not answer. Server might be down or something.
