My hardware: Dell XPS 13 (9343)

I am able to reproduce the error using
$ sudo dpkg-reconfigure grub-efi-amd64-signed 

Then I thought what might be different on my system, because this kind
of error should normally affect more people. I remembered a BIOS update
some weeks ago. Before attempting to downgrade I had a lucky guess and
deleted the BIOS update file (9343_A17.exe) from /boot/efi - et voila:
the problem seems to be gone.

Can other affected people please try to check their /boot/efi partition
for unneeded files?

I updated my BIOS using this method (putting the exe file from the Dell
support page to /boot/efi and then choosing BIOS update in the F12 boot
menu) since months or even years. So this issue definitelly is a
regression within Ubuntu.

BR, Michael
