[Bug 1639458] Re: package shim-signed 1.21.3+0.9+1465500757.14a5905.is.0.8-0ubuntu3 failed to install/upgrade: subprocess installed post-installation script returned error exit status 1

[Steve Langasek]

Something has caused the shim-signed package to be installed on your
system, despite your system not being detected as an EFI system.  We
have seen reports of this, but have yet to identify the source of the
problem.  Could you attach the output of 'sudo dmidecode' from your
system?  That might help.
