I'd disagree slightly - I think he was right to try "upgrade" first -
because it won't do anything scary.  In this case, though, it wouldn't do
anything at all (probably because there's a libc transition in there).

After upgrade, dist-upgrade.  There's certainly no way you can just randomly
install a single package and expect everything to work.

As for the GPG thing, it's exactly what it says - such errors occur either
when you can't retrieve the keys (stupid firewall at work blocks such
traffic!) or when the keys are actually not valid (a problem I've seen too
often in Ubuntu), and so you need to be able to assure yourself these are
genuine packages.  It's never _likely_ to be a problem, but somebody
_could_ potentially be trying to load trojans to your system.  It's
reasonably safe to assume that it has nothing to do with your problem.
