Apt follows it's own extremely strict requirement of leaving no
unsatisfied dependencies after any given operation to the point of
self-termination. When doing dist-upgrades with apt you should always 
point it to all the target distro version's third party repositories 
you're using, not just the OS itself to avoid these things (and actually 
get a much smoother upgrade). Mm.. that's a bit unclear sentence perhaps, 
what I mean is that if you're using lets say RHL 9 with freshrpms and want 
to upgrade to FC1, you need to point apt to FC1 os component AND freshrpms 
built for FC1 before proceeding with the upgrade.
