When I tried to upgrade one of my PCs (13.10->14.04) I met this problem and had to repair everything manually. Now I have three more PCs to upgrade: one running 13.10 and two running 12.04 LTS. Is there a procedure that can be used on these hosts _before_ upgrade to guarantee that upgrade will work without any problems? For example, assuming that I need grub-pc, will the following prevent reliably problems during upgrade:
1. run 'dpkg-reconfigure grub-pc'
2. Start the upgrade
