You're welcome.

I assume that you mean "apt-get -f install" not "dpkg -f".

I would've run "apt-get dist-upgrade" first (that's what I meant by
"updating"; sorry) and then run "apt-get -f install" in case it was
needed. You might have found that you needed the latter first but that
was what my bad wording implied.
