I'm now doing:
apt-get install apt (to upgrade apt)
apt-get upgrade
apt-get dist-upgrade
And I don't really see any difference (I haven't tested all the packages
that were failing).
Good examples of packages that fail are pyrex-mode and
python-application. Both get removed during apt-get dist-upgrade, but
can be installed without removing any package after that.
