package shim-signed 1.48+15.4-0ubuntu5 failed to install/upgrade: »installiertes shim-signed-Skript des Paketes post-installation«-Unterprozess wurde durch Signal (Beendet) getötet

[Christian Spoo]

shim-signed was to be updated during regular package update operations. I tried this through the GUI and wanted to select my only EFI partition for GRUB to be installed to. That failed and the debconf GUI didn't let me finish the installation.

Thank you for your bug report. Why did it fail, and what steps did you take?

[Christian Spoo (tehplague)]

the debconf GUI ignored that I checked the only grub partition to install GRUB onto. Next screen asked if I wanted to skip GRUB installation altogether which I did not.
Since I could not leave the GUI I terminated the process and performed

dpkg-reconfigure shim-signed

on a fresh terminal. It asked the same question but was happy with my answer and the GRUB re-installation succeeded without any problems.
