Public bug reported:
I had 2.6.35-25 installed on a few machines, and found it wasn't really
what I needed, and wanted to go back to 2.6.23-xx, so I just uninstalled
(apt-get remove --purge) the 2.6.35 image. This ran grub-update as
normal. After reboot, grub tried and failed to start 2.6.35-25.
Rebooting on a rescue CD showed /boot/grub/grub.cfg was the same old one
since I installed 2.6.35-25. Running grub-update manually didn't change
this either. The fix was to run grub-mkconfig -o /boot/grub/grub.cfg
directly, even though the documentation at
https://help.ubuntu.com/community/Grub2 says this is done with grub-
update.
I think this needs to be fixed, because without it, it may render a
system unbootable. If grub-update could be made to check for the
presence of the kernel files, or perhaps just run grub-mkconfig for each
update, that'd be preferable.
