Bug Description

I've upgraded my htpc box several times but only recently i found out im still on the generic 12.04 kernel. So i tried udating grub

root@htpc:/# update-grub
GRUB >= 2.00 has been unpacked but not yet configured.
grub-mkconfig will not work until the upgrade is complete.
It should run later as part of configuring the new GRUB packages.

I then tried the usual: apt-get -f install, reinstallation and removal of grub-pc, but still the error. grub-install works fine

root@htpc:/home/bart# grub-install /dev/sda
Installing for i386-pc platform.
Installation finished. No error reported.

I started digging around a bit in /usr/sbin/grub-mkconfig and found:

if fgrep -qs '${GRUB_PREFIX}/video.lst' "${grub_mkconfig_dir}/00_header"; then
  echo "GRUB >= 2.00 has been unpacked but not yet configured." >&2
  echo "grub-mkconfig will not work until the upgrade is complete." >&2
  echo "It should run later as part of configuring the new GRUB packages." >&2
  exit 0

but GRUB_PREFIX is nowhere defined??? Is this file delivered like that in the distribution? If so, it looks like a pretty silly bug. Anyway, I've added:
 and now everything works fine.

That should not have made any difference since the script is not actually referencing GRUB_PREFIX since it was removed. The script is checking to see if /etc/grub.d/00_header still references it, which it shouldn't as it has been removed. Does your 00_header still reference it? If so something must have gone wrong in the upgrade somewhere. Purge grub-common and reinstall and it should reinstall that file which should no longer reference that variable.

Thanks for the swift reply. Purging grub-common (and manually removing /boot/grub) following by an install of grub-pc indeed did the trick. Most have gone wrong in one of the previous upgrades as you suggested.

Only one warning remained during install, but that easy to fix:
Warning: Setting GRUB_TIMEOUT to a non-zero value when GRUB_HIDDEN_TIMEOUT is set is no longer supported.

Could you please attach /var/log/dist-upgrade/main.log and /var/log/dist-upgrade/apt.log if you still have them from the upgrade? This may help figuring out what went wrong.

Hey, the same thing is happening to me. I saw that @Phillip Susi said that "The script is checking to see if /etc/grub.d/00_header still references it, which it shouldn't as it has been removed". Do you mean that the script has been removed or that the script has changed and is no longer referencing it ?
I am doing an upgrade from 12.04 to 14.04 then to 16.04. From what i saw, the 00_header does not change from 12 -> 14 -> 16.
