[Bug 1679784] Re: 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

The error in your log is:

Processing triggers for shim-signed (1.27~16.04.1+0.9+1474479173.6c180c6-1ubuntu1) ...
Running in non-interactive mode, doing nothing.
dpkg: error processing package shim-signed (--configure):
 subprocess installed post-installation script returned error exit status 1

This shows that shim needs to interact with you in order to disable
secureboot on your system; this is correct, if you are installing the
nvidia modules you need SB disabled so that kernel module signatures are
not enforced.

And your DpkgHistoryLog.txt shows that dpkg is being run via aptdaemon.

Start-Date: 2017-04-04  18:20:35
Commandline: aptdaemon role='role-commit-packages' sender=':1.100'
Install: libcuda1-375:amd64 (375.39-0ubuntu0.16.04.1, automatic), libvdpau1:amd64 (1.1.1-3ubuntu1, automatic), vdpau-driver-all:amd64 (1.1.1-3ubuntu1, automatic), nvidia-prime:amd64 (0.8.2, automatic), libxnvctrl0:amd64 (361.42-0ubuntu1, automatic), lib32gcc1:amd64 (1:6.0.1-0ubuntu1, automatic), libc6-i386:amd64 (2.23-0ubuntu7, automatic), screen-resolution-extra:amd64 (0.17.1, automatic), mesa-vdpau-drivers:amd64 (12.0.6-0ubuntu0.16.04.1, automatic), ocl-icd-libopencl1:amd64 (2.2.8-1, automatic), libjansson4:amd64 (2.7-3, automatic), bbswitch-dkms:amd64 (0.8-3ubuntu1, automatic), nvidia-opencl-icd-375:amd64 (375.39-0ubuntu0.16.04.1, automatic), nvidia-375:amd64 (375.39-0ubuntu0.16.04.1), nvidia-settings:amd64 (361.42-0ubuntu1, automatic)

So clearly, aptdaemon is being run in a context that has no debconf
frontend.

This is really not acceptable that we have such bugs after all this
time.

When I run update-manager (AKA Software Updater) here, I see that
aptdaemon does get run with the correct environment of
'DEBCONF_PIPE=/tmp/aptdaemon-jcxymk3r/debconf.socket
DEBIAN_FRONTEND=passthrough'.  So this doesn't appear to be a problem in
the version of update-manager that I have here.

Can you please describe exactly how you went about installing the nvidia
driver, step by step?  What did you click on at each step, etc.

To work around the problem on your system now, you should be able to run
'sudo dpkg --configure -a' from a terminal to go through the process of
disabling SecureBoot.

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.
