This bug is *NOT* quite a duplicate, as far as I can tell.

The other bug (199086) discusses methods of trimming the list of kernels either because the list is too long, or because update-manager fails during a normal kernel upgrade. This bug is because a VERSION UPGRADE fails in the middle, and MAKES THE SYSTEM UNUSABLE and unrecoverable by anyone without high technical skills.

Whether or not the kernel list is pruned, the version upgrade process needs to avoid leaving the system in an unusable state. Which, as far as I can tell, would mean checking /boot before the upgrade even starts.
