[Bug 1469995] Re: grub-efi-amd64-signed Forced Uninstall Causes Boot Failure

[Fabricio Biazzotto]

Also it seems to be impossible to force the old 2.02~beta2-22ubuntu1
version, at least on Synaptic.

Title:
  grub-efi-amd64-signed Forced Uninstall Causes Boot Failure

Status in grub2-signed package in Ubuntu:
  Confirmed

Bug description:
  Yesterday, I tried to run an apt-get install when it said it could continue because of some "partial" something or other and I noticed it wanted to remove "grub-efi-amd64-signed".
  I went ahead and let it update on it's own as it desired.

  Then a little while ago I had to reboot for an unrelated reason, but I
  find myself no longer able to boot. Not just not able to boot, but
  there is no GRUB or EFI shell.

  Boot-Repair from Live CD wouldn't complete due to "purge cancelled" for "grub-efi-amd64-signed".
  While in Live-CD, I'd chroot to my system and run "grub-install" and "update-grub", and while they both succeeded, nothing had changed on boot.

  I ended up disabling Secure Boot for now, but wanted to let you know
  something went horribly wrong.
