[Bug 2117535] Re: package grub-efi-amd64-signed 1.202.5+2.12-1ubuntu7.3 failed to install/upgrade: installed grub-efi-amd64-signed package post-installation script subprocess returned error exit status 255

Thanks for taking the time to report this bug and helping to make Ubuntu
better. We appreciate the difficulties you are facing, but this appears
to be a "regular" (non-security) bug.  I have unmarked it as a security
issue since this bug does not show evidence of allowing attackers to
cross privilege boundaries nor directly cause loss of data/privacy.
Please feel free to report any other bugs you may find.

** Information type changed from Private Security to Public
