Until now I got apturl to known if a package is virtual or not and display a different error message if it is (you can test this on revision 48 of my branch). I'll now see if I can get it to choose a real package.
Fixing this requires directly accessing the internals of python-apt, but it shouldn't be too much of a problem (debimg does the same for its dependency resolver).
I'm working on this.
