[Bug 1878443] Re: package shim-signed 1.40.3+15+1533136590.3beb971-0ubuntu1 failed to install/upgrade: installed shim-signed package post-installation script subprocess returned error exit status 1

[Steve Langasek]

Unfortunately there is nothing in the attached dpkg log that shows
output from the shim-signed maintainer scripts to explain why this
failed.  Can you attach the full /var/log/apt/term.log from the affected
system?
