[Bug 1799767] Re: grub menu not showing with SecureBoot enabled after update

[Steve Langasek]

Ok.  Crucially, this shows that you have the
1.37~18.04.2+15+1533136590.3beb971-0ubuntu1 version of shim-signed
installed, which was released on October 11 to bionic-updates;
superseding version 1.34.9.2 which was there previously.

Why was the shim-signed package not installed?  This is the package that
\EFI\UBUNTU\SHIMX64.EFI is installed from, so for it to be absent
suggests something was wrong with your upgrade process.  Are you sure
that the \EFI\UBUNTU\SHIMX64.EFI which was installed on your EFI System
Partition at the time you encountered this problem was the one from
shim-signed 1.37~18.04.2+15+1533136590.3beb971-0ubuntu1 ?  (E.g.: if you
disable CSM again now, does the problem reappear?)

Title:
  grub menu not showing with SecureBoot enabled after update

Status in shim-signed package in Ubuntu:
  New

Bug description:
  Started with Ubuntu Version 14.04 I always had SecureBoot enabled and also CSM (compatibility support module) enabled in BIOS of Motherboard ASUS Z170-A, BIOS 3802 03/15/2018.
  On October, 13th i did the updates that UpdateManager showed in the morning.

  After rebooting in the evening, afterwards the BIOS splash screen there was only a black screen. No grub menu, no booting in SecureBoot mode.
  I tried different repairs (tool boot-repair, reinstalling grub, installing signed kernel transitional packages and so on, but nothing would help.

  At the end I found out out, that switching CSM to disabled "solved"
  the problem and it is now reproducible: Switching CSM on, no secure
  boot, switching off, secure boot works.

  But I did not wont to switch CSM off.

  I also tried to get some help at ubuntuforum. But no luck.

  See here

  Since today I think it's a bug in shim or grub, because at the morning
  of Oct, 13th these have been updated.

  Regards

  Frank
