[Bug 1679784] [NEW] package shim-signed 1.27~16.04.1+0.9+1474479173.6c180c6-1ubuntu1 failed to install/upgrade: subprocess installed post-installation script returned error exit status 1 Crashed on changing from Xorg video driver to NVIDIA driver

[Amos]

Public bug reported:

I've encountered this repeatedly.

In the first installation -- on updating via Software Updater, this
crashed on upgrading the shim-signed package.

On suggestions from here:

I upgrade the system via CLI, i.e. dist-upgrade. This seemed to work,
however when I now try to swap the display driver, from xorg --> nvidia.
This now triggered the same issue.
