View Full Version : Installation Problems with 18.10 on Thinkpad X1 Yoga 3rd Gen

November 2nd, 2018, 10:27 PM
Currently, when I try booting with an 18.10 ISO image I copied to a USB flash drive, in order to run the installer on my new laptop, I get the following error message:

Failed to open \EFI\BOOT\mmx64.efi - Not Found
Failed to load image \EFI\BOOT\mmx64.efi: Not found
Failed to start MokManager: Not Found
Something has gone seriously wrong: import_mok_state() failed
: Not Found
The computer then shuts down.

How I got here:

Downloaded the ISO from the website
Used Rufus 3.3 to copy it to a bootable USB flash drive
Ran through the installation and selected third party drivers on the Updates and other software page
Was prompted to create a password, something to do with UEFI and driver signing
Proceeded to the Installation Type page
Canceled the installation since I decided it was prudent to create a Windows recovery drive in case I wanted to go back to Windows (I don't plan on dual booting.)
Tried to boot with the USB flash drive, got the error above.

What I have found:
This bug (https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/1798171), which is marked fixed. It would seem that it may fix my issue, but I'm not sure, and I don't know when the fix will be propagated to a new installation image. Would that be when the next version is released, say 18.11?

I installed 18.04.1 instead. No notable problems to report, it worked like a charm. (Expect for some issues with my external Thunderbolt 3 dock, but that's another story.)
