[Bug 1817746] Re: package shim-signed 1.33.1~16.04.4+15+1533136590.3beb971-0ubuntu1 failed to install/upgrade: subprocess installed post-installation script returned error exit status 128

[Steve Langasek]

Thanks for reporting this bug and helping to improve Ubuntu.

At the point the logs start to show errors, the shim-signed package
should have been prompting you to choose a password to use for enrolling
a key in your firmware that is used to sign your dkms kernel modules.
Were you shown this prompt?
