[Bug 2023429] Re: package shim-signed 1.40.9+15.7-0ubuntu1 failed to install/upgrade: installed shim-signed package post-installation script subprocess returned error exit status 1

[Alex Murray]

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
