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

[Max Wolf]

I upgraded three machines and ran in the problem on just one.
boor-repair didn't work for me, but after a grub-install with the live-cd i got to the grub shell and succeeded booting manually.
running grub-install again from within 14.04 fixed it eventually.
I learned a lot about grub, but lost around a day sorting this out. 
(I work as a half-time linux sysadmin, but i never had to deal with grub before).

This article helped me to understand how to boot manually: https://help.ubuntu.com/community/Grub2/Troubleshooting
But i doubt, that most end users can deal with this.

What concerns me more than the actual bug is the handling of this bug.
It's unclear to me, if somebody is taking care of this. I agree with the high priority. 
This will make many users ran away from the distro of from linux in general.
psusi seems to be involved, but refuses to be helpful.
In a software company, somebody would would talk to his boss. But what is the escalation procedure here?

It seems, that none of the commenters here really understands what's causing this.
This requires a senior engineer with grub/updater know-how, who is willing to help.

My guess is, that it's not grub2 but the updater, that's causing this.

  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:

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"
