​Of course,

Once the OS was installed. Reboot (at which point I probably should have
disabled the Secure Boot in the BIOS).

I avoided using the gui to do the updates, because it hung during the
update in my previous attempt (rendering the system unbootable -- went to
mauve screen with no text [not sure if this would have been resolved by
disabling SB in BIOS though as I just went for a re-install]). Looking
around it was suggested that I should try using the CLI to do the upgrade.

I think the main issue was the option to disable secure boot during the
install process did not persist, so when upgrading and installing certain
things that needed SB disabled this caused a problem. I'm not sure why this
worked with the CLI but didn't than the Software Updater.

So I did this (and while it did work):

   1. Install OS
   2. $ sudo apt-get update
   3. $ sudo apt-get dist-upgrade
   4. opened the Settings >> Software & Updates >> Additional Drivers
   [selected the now installed NVIDIA driver in place of the Xorg one]
   5. Reboot
   6. Disable Secure Boot in BIOS
   7. Fin.


​But probably should have done this:

   1. Install OS
   2. ​Reboot​

   3. ​
   Disable Secure Boot in BIOS​

   4. $ sudo apt-get update
   5. $ sudo apt-get dist-upgrade
   6. opened the Settings >> Software & Updates >> Additional Drivers
   [selected the now installed NVIDIA driver in place of the Xorg one]
   7. Reboot
   8. Fin.

​
Anway hope that helps.

Title:
  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

Status in shim-signed package in Ubuntu:
  Incomplete

Bug description:
  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.
