You seem to have a private squeeze repository there on 192.168.0.4,
which is apt-pinned via /etc/apt/preferences to 3.3.8b.  The specialness
of priorities over 900 leads me to guess that you might have had to do
a downgrade at some time and this situation may be left over from that.

You'll need to downgrade the priority of that repo to no higher than 500,
perhaps by removing it entirely from /etc/apt/preferences, either that
or increase the Trinity repo's priority to match.

I recently upgraded 3.5.12 directly to 3.5.13.1 on squeeze and it all
went very cleanly, so hopefully once you have done that you should be
able to upgrade the rest of the way.
