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

[Cian Davis]

Adam,
Apologies, I had fixed the problem by the time you posted and I didn't realise outputs from those commands would have been helpful. Thanks for taking the time to try and sort the issue.

Philip,
I installed my system from scratch a few months ago with Saucy. I applied updates as they came up and upgraded to Trusty this morning when offered by the system using the built-in ugrader. Grub was installed and working fine on my disk before I upgraded. Post reboot, all I got was a grub shell and the reported error. I don't know what you're referring to about grub-pc/install_devices and how or why I would change it. I haven't changed disk configs since I installed.

If this isn't a defect in the software, I don't know what is. It may be
because of a few unlikely elements coming together. It may not actually
be a problem with the grub package so the bug should be refiled. But
there is certainly a problem somewhere - and it's a big one.

Dismissing people so vigourously when they report a bug is pretty
disappointing. It's certainly put me off ever trying to assist with a
bug again. I can fix the error myself but I've been encouraged by Ubuntu
devs I know to help with bug reporting so that the overall quality of
the software improves and new users don't have quite such a steep
learning curve and will see Linux as a real alternative.

But I obviously have a naive view of the community - the priority is to
close bugs saying why they shouldn't have been filed in the first place.

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

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"
