[Bug 1694986] Re: (unattended-upgrade, already-installed dkms modules) package shim-signed 1.28+0.9+1474479173.6c180c6-1ubuntu1 failed to install/upgrade: subprocess installed post-installation script returned error exit status 1

[Steve Langasek]

Thank you for the report.  This shows that you had an unattended upgrade
that ran and upgraded the version of the nvidia dkms module that you
have installed; and that this triggered a request from shim to disable
SecureBoot on your system, because dkms modules are incompatible with
SecureBoot currently.

Do you remember being prompted previously about turning off SecureBoot?
Did you elect not to turn off SecureBoot?  Or, did you choose the option
to disable SecureBoot, but not confirm this selection on reboot?

** Summary changed:

- package shim-signed 1.28+0.9+1474479173.6c180c6-1ubuntu1 failed to install/upgrade: subprocess installed post-installation script returned error exit status 1
