[Bug 1961641] Re: package shim-signed 1.34.9+13-0ubuntu2 failed to install/upgrade: installed shim-signed package post-installation script subprocess returned error exit status 1

[Steve Langasek]

The version of shim-signed that you were upgrading to is the release
version of shim-signed in 18.04.  This version of shim-signed cannot be
supported; it is 4 years old, and missing all security updates to shim
that have been released in the past 4 years.  It will quite simply
become unbootable at a future date.

The issue you're reporting is one that was fixed at some point in the
history of bionic.  You should have bionic-updates enabled when
upgrading between releases.

The simplest way to achieve this is to use do-release-upgrader or
update-manager to manage the upgrade, which appears not to have been
done here.
