I just ran into this bug, tried a suggestion from here
(https://askubuntu.com/questions/89710/how-do-i-free-up-more-space-in-
boot) which resulted in multiple errors, and me being sent here.
It seems to me that this should be taken care of automatically by the
kernel with the upgrading process.
Terminal output of the above suggested method:
