Tom, Ralf,
@Thanks. Here is the output:

I can not do much with that.
@Ralf,
It is an interesting option you mention. However, it's a hell of a job 
to weed out which packages need :i386 and are they replaced by x64 packages?
Interestingly, your suggestion showed a lot of i386 packages a.o. mysql.
I'll give the output here, which is quite lengthy.

You might want to run 'apt-get -f install' to correct these:

E: Unmet dependencies. Try 'apt-get -f install' with no packages (or 
specify a solution).

What I don't understand is why "apt-get -f install" isn't working or is 
there an conflicting situation even deeper in the chain of events.
