I started in synaptic, first upgrading Debian tools and the kernel,
that blew out synaptic with dpkg errors and I went to the console and
ran apt-get -f install and then dpkg --configure -a, back in business, I
had to do that a few times and then able to switch to using the new apt
and clean up with upgrade-system, it took sometime but here I am with a
clean, upgraded and configured system.
Cheers,
