SUMMARY STEPS TO REPRODUCE 1. Download latest release from the KDE Neon site. 2. Create bootable USB 3. When it boots gives error missing mmx64.efi and the laptop shuts down. OBSERVED RESULT Laptop shuts off EXPECTED RESULT To boot without problems SOFTWARE/OS VERSIONS Linux/KDE Plasma: (available in About System) KDE Plasma Version: Latest to date 04.09.2020 KDE Frameworks Version: Latest to date 04.09.2020 Qt Version: Latest to date 04.09.2020 ADDITIONAL INFORMATION It's "fixable" if you copy from the usb EFI/boot grub64.efi to another place, rename it to mmx64.efi and put it back to the usb EFI/boot folder.
What does `ls /sys/firmware/efi/efivars/ |grep Mok` have to say?
(In reply to Harald Sitter from comment #1) > What does `ls /sys/firmware/efi/efivars/ |grep Mok` have to say? Sorry on another distro already so can check it. And don't think it was even possible to check because after the message that mmx64.efi is missing the laptop shuts down.
You'd check that on a running system.
(In reply to Harald Sitter from comment #3) > You'd check that on a running system. Do I need to install the OS or from Live USB will be enough? If Live USB is an option I can make it again so I can help you fix this for other users.
Any running linux is good enough. It doesn't have to be neon, it doesn't have to be installed.

The command ls /sys/firmware/efi/efivars/ |grep Mok gives me no result at all on installed Kubuntu (what I am using right now). ls /sys/firmware/efi/efivars/ gives me the result down. Hope it helps.

Forgot to mention my secure boot is off right now.
Got the latest ISO today and it installed without any problems.
Thanks for the update; changing status.
Git commit b0846c92dec97f4483ed16042ac67729e7e41ce1 by Harald Sitter. Committed on 11/11/2020 at 13:41. Pushed by sitter into branch 'Neon/release-lts'. attempt to inject the MM image file for secureboot this is missing from upstream live-build unfortunately but at least on ubuntu bases we need it included as the shim.efi will load the mm.efi when it finds certain Mok related nvars being set MM being the mok manager for doing key management. this notably can happen when the user installs ubuntu with proprietary hardware that requires unsigned kernel modules. to still carry out secureboot it needs to enroll a custom key. this is done through the MM. the installation will set a bunch of nvars that get checked by the shim on the next boot and the shim then starts the mm and the mm will enroll the key. if the actual target system shim is never run but instead one directly boots into another live iso that iso's shim would be the one in need of running the mok, hence the need for the mm.efi as otherwise our shim would attempt to load the MM on account of finding Mok related vars and then falling flat on the face because the mm*.efi file doesn't exist this is pretty far out as far as unfortunate chains of events go M +10 -0 scripts/build/lb_binary_grub-efi https://invent.kde.org/neon/forks/live-build/commit/b0846c92dec97f4483ed16042ac67729e7e41ce1
Seems that should fix it moving forward. /usr/sbin/update-secureboot-policy --new-key mokutil --import /var/lib/shim-signed/mok/MOK.der results in Mok vars in /sys/firmware/efi/efivars/ and mok manager starting on next run, this now also works correctly with a test ISO I've just built.
