[Bug 1455754] Re: Wrong signature on EFI Bios after dist-upgrade

[Steve Langasek]

ok, this shows grub-efi-amd64-signed 1.34.2+2.02~beta2-9ubuntu1.1 being
uninstalled at the time that grub-efi-amd64 2.02~beta2-9ubuntu1.2 is
installed. Do you have trusty-proposed enabled in your apt sources?
(grep trusty-proposed /etc/apt/sources.list)  You appear to have
installed grub-efi-amd64 2.02~beta2-9ubuntu1.2 on May 14, which is two
weeks before it was released to trusty-updates (on May 27).

Users should not in general have the -proposed pocket enabled on their
systems, and should not apt-get dist-upgrade to the packages in
-proposed, because packages may be temporarily uninstallable with
-proposed.  This problem never affected users in trusty-updates; to fix
your system, you just need to re-install the grub-efi-amd64-signed
package.

Title:
  Wrong signature on EFI Bios after dist-upgrade

Status in shim package in Ubuntu:
  Invalid

Bug description:
  Hello,
  I am running Ubuntu 14.04 since April 2014. This week, I ran apt-get dist-upgrade, as there were efi-bios and grub updates pending.
  Update ran fine, but after reboot my EFI Bios complains that the signature is wrong and it refuses to run Grub.
  To access Grub, I must disable the security in the Bios.
  Using Google, I can just find users facing a similar issue upgrading from 13 to 14.04, but they got an error message, not a wrong signature.
  It seems the signature has not been updated after the grub update.
