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

[Teo]

So, I'm getting tired of always unchecking Grub from automatic updates
just to be sure that my system won't break again at the next reboot, and
I would also like to upgrade to Ubuntu 14.10, which I have been delaying
so far for the same reason (and then, 15.04 must be almost out). As a
remainder: I was one of the people whose working dual boot system was
screwed up when upgrading from 13.10 to 14.04 (because of a
"misconfigured system" according to Phillip Susi, which I doubt, but if
it is the case, it was misconfigured because of some bug in the first
place)

So, is this what I need to do in order to prevent my computer from being bricked again by an upgrade?
> dpkg-reconfigure grub-pc
Will this ensure that updating grub and upgrading to 14.10 won't screw things up again?

And then I guess that will ask me for some parameters, or to choose
something. If so, what command should I run to figure out what my
current perfectly working configuration of grub is and make sure it is
preserved, and/or to figure out the correct answer to whatever dpkg-
reconfigure prompts may show up?

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

Status in grub2 package in Ubuntu:
  Triaged

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"
