After that, I rebooted to the Super-UEFIinSecureBoot-Disk_v3 USB drive.I was then prompted for a private password for the imported keys.Sudo mokutil -import ~/Desktop/ENROLL_THIS_KEY_IN_MOKMANAGER.cer In an Ubuntu LiveDVD environment, I copied the ENROLL_THIS_KEY_IN_MOKMANAGER.cer certificate from the USB drive to my desktop, and then ran this command:.First, I disabled Secure Boot in the UEFI BIOS to allow me to run from my USB drive.I found this Fedora page, which mentioned using the mokutil command to initiate the MOK key registration process and then using the MOKManager to complete the enrollment.

There is still an issue with the UEFIinSecureBoot image and my PC, but I do have a temporary work-around. I found a solution of sorts that got my MOK keys registered for my PC, though it required booting into Linux to get it accomplished.
