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

[frank]

Output of apport-collect now is
...
Package shim-signed not installed and no hook available, ignoring
Gtk-Message: 21:00:40.534: GtkDialog mapped without a transient parent. This is discouraged
...

And yes, it's true, at the moment it is not installed and the behaviour is as I described first.
But I'm sure, that the behaviour was the same when shim-signed had been installed some days ago. If you want, I can install it, try reeboot with CSM enabled and with CSM disabled and tell, what I have found out then.

Title:
  grub menu not showing with SecureBoot enabled after update

Status in shim-signed package in Ubuntu:
  Incomplete

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.

  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
