[Bug 1289977] Re: Ubuntu 14.04 Update breaks grub, resulting in "error: symbol 'grub_term_highlight_color' not found"

[RichardNeill]

I reported this on Mageia; you may find the following helpful.
https://bugs.mageia.org/show_bug.cgi?id=12423

As to what is happening, it has got *nothing* to do with the terminal_highlight_color.
Grub has 2 parts:
   The early stage, installed in the drive's bootsector
   The rest of the modules, installed in /boot/grub

These two are getting out of sync, and the ABI symbol mismatch is because there is an older version of one than of the other.
I suspect that:

1. The grub package, which installs binaries into /boot/grub  is being updated
2. Something is failing to correspondingly update /dev/sdX's boot sector
3. No warning is emitted.

Title:
  Ubuntu 14.04 Update breaks grub, resulting in "error: symbol
  'grub_term_highlight_color' not found"

Status in Ubuntu Release Upgrader:
  New
Status in “grub2” package in Ubuntu:
  Confirmed

Bug description:
  The update from 13.10 to 14.04 via update-manager broke grub for me,
  which resulted in the grub error:

  "symbol 'grub_term_highlight_color' not found"

  on startup.

  To fix the problem I had to boot to my persisting Ubuntu installation
  (e.g. using Super Grub Disk) and had to reinstall grub on my boot
  partition: "sudo grub-install --recheck /dev/sdx"
