Yup!  did that and the messages disappeared, even after I again did "sudo 
apt-get -f dist-upgrade"

Well, it ain't complainin no more!  :-)
Still no X, though  :-(
More accurately, X starts, but no display manager.

Fortunately I have an 80G HD with some spare space, so have been able to 
install a fresh Hoary which I am using to send this message.  But still no 
working Breezy.  :-(

Only thing I can now think of is to empty the original ubuntu partition and 
install Breezy from scratch.  However, what might grub make of this?  Will 
the grub from breezy auto-detect existing systems and replace the existing 
grub without any problem?  If so, fine.  If not, what should I do?

Thanks for all help so far.
