[Bug 1802570] Re: Grub install fails on Apollo Lake Tablet PC

[Joey van Hummel]

I've done more extensive testing and it seems that when installing grub
with the --no-nvram option, all goes well. Setting EFI vars is what
mucks up.

** Summary changed:

- Grub install fails on Apollo Lake Tablet PC
+ Grub install fails when writing to NVRAM on Apollo Lake Tablet PC

** No longer affects: ubiquity (Ubuntu)

Title:
  Grub install fails when writing to NVRAM on Apollo Lake Tablet PC

Status in grub-installer package in Ubuntu:
  New

Bug description:
  When installing ubuntu 18.10 on my tablet-PC, the grub installer
  causes kernel messages to appear and then hangs indefinitely. I've
  done some research and found that Grub apparently doesn't play well
  with Apollo Lake based (tablet) PC's, but can't find a bug report on
  here.

  I've used the "sudo ubuntu-bug -w" command to report this bug. I
  realise this is probably not a lot to go on, but I'm not afraid to get
  a little hands-on and do more investigative work per your instructions
  / suggestions.

  As a sidenote, I also tried installing Elementary OS, which runs into
  the same issue but at least reports that there was an issue. Ubiquity
  on 18.10 simply hangs flat out. The UI is still responsive, but the
  install process will have stalled.
