[Bug 1474203] Re: package shim-signed 1.6+0.4-0ubuntu4 failed to install/upgrade: subprocess installed post-installation script returned error exit status 1

[Steve Langasek]

This is a bug in the shim-signed package.  Versions of shim-signed in
14.04 and later rely on the --target feature of grub-install, which is
only available in grub 2.00 and above.  So shim-signed should have a
versioned dependency on grub2-common.

Your attached logs also show that you have tried to run 'apt-get
upgrade' to upgrade between precise and trusty.  Please note that this
is absolutely unsupported.  'apt-get upgrade' will not install new
packages, which is a requirement when upgrading between major releases.
You must at minimum run 'apt-get dist-upgrade'.  It is recommended that
you run 'do-release-upgrade' for commandline upgrades between releases,
or use 'update-manager' for desktop upgrades.
