It's not so simple, as you have already noticed. If the packages you 
installed didn't create dependency problems, things would go as smooth as 
you expected, however this looks like it's not the case for you. The 
upgrade process can only predict results based on what packages it knows, 
and that's official packages only.

You didn't state which packages you installed from 3rd party repos, so 
it's impossible to tell what the problem is exactly, but I think you 
should remove them, and reinstall them after the upgrade.

I believe there *is* a warning about unnoficial repos, but I'm sure what 
it does when you already have installed unofficial packages. It should be 
a fairly complex situation to deal with, automatically, because you could 
install an unofficial version of a package provided (say, a backport, or 
a locally generated package).
