[Bug 1407790] [NEW] GRUB >= 2.00 has been unpacked but not yet configured.

[mca]

Public bug reported:

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 at 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 at 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
fi

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:
GRUB_PREFIX="/boot/grub/i386-pc"
export GRUB_PREFIX
 and now everything works fine.
