package grub-efi-amd64-signed 1.187.2+2.06-2ubuntu14 failed to install/upgrade: installed grub-efi-amd64-signed package post-installation script subprocess returned error exit status 1

Not sure what happened, after restart and update the system reported that there was an error and updates were not completed. However everything is functioning correctly.

Thought I may as well report whatever issues there may be as I would be comfortable with the system well up to date to avoid any system vulnerabilities as well as unexpected crashes or failures.

Same as on 18.04 LTS!
Worked fine until the latest update...

Status changed to 'Confirmed' because the bug affects multiple users.

My problem was with the --auto-nvram in the postinst script contained in the .deb package:
   grub-install --target=$target --auto-nvram
Replaced it with --no-nvram and it worked...
Not sure it's the right thing, though, nor why --auto-nvram would fail.

And "Dima L" comment worked
