To get around this problem  in the past I have used the technique of
deleting some of the old kernel files in /boot, using something like
sudo rm /boot/*-a.b.c-dd*
then
sudo apt-get install -f
sudo apt-get install linux-generic

You might want to try ls rather rm initially just to check it finds
the right files.
