Thanks, indeed, some changes I made to /etc/default/grub seem to be responsible for this. While I'm not exactly sure what exactly caused the problem... after reverting the changes I no longer have problems updating kernel images.
Thanks for taking the time to review this. It seems this problem was entirely due to 'user error'. Nothing wrong with Ubuntu :-) Please close ticket.
