UEFI MOK Management failure

I have observed through the last monthes failures when booting.
EFI failure, file not found …
“Failed to start MokManager: Not Found
Something has gone seriously wrong: import_mok_state() failed: Not Found”

The problem seems to be known ( https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/1845466 ) and seems to be solved since GRUB 2.04.
My secure boot is disabled in BIOS.
I think I see that issue when Kernel updates have been done. (need to observe)
Boot is possible via USB. After boot from USB, problem is solved so far.

Have a read of this thread: https://forums.opensuse.org/showthread.php/543433-update-killed-bootloader

yes, that is exact what happen.
When update kernel we get this failure - just tried again without update: all well.
I will try that, copy MOKManager
_Assuming you cannot fix your firmware, workaround is to copy MokManager.efi from \EFI\openssue\ to \EFI\Boot. _
