apport information
** Tags added: apport-collected
** Description changed:
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.
