This bug does **not** occur if you install Ubuntu normally. It only
appears to strike OEM installs.

Title:
  MOK-enrolled Secure Boot keys are not saved on the installed system
  when doing an OEM installation

Status in shim-signed package in Ubuntu:
  New

Bug description:
  Steps to reproduce:

  1: Enable Secure Boot.
  2: Install the latest Ubuntu Kinetic ISO using the OEM installation option. Make sure to allow the installation of proprietary drivers and choose to configure Secure Boot.
  3: Reboot and do the key enrollment with mokutil.
  4: Reboot again, then prepare the system for use by the end user (just double-click the shortcut), then reboot again.
  5: Finish setup.
  6: Run "ls /var/lib/shim-signed/mok".'

  Expected result: The files "MOK.priv" and "MOK.der" should be shown.

  Actual result: The listed directory is empty.

  Notes:

  This did NOT happen to me on a non-OEM installation. I noticed it
  attempting to manually sign a driver while grappling with bug 1991725.
  It probably will interfere with the use of DKMS modules even if they
  get installed and signed properly the first time.

  For some reason "ubuntu-bug shim-signed" thought that shim-signed
  wasn't an official Ubuntu package, so I'm reporting this without using
  ubuntu-bug. I can provide any desired log files from the test system
  upon request.
