Suddenly getting mok.c dump on every boot just before the grub menu

Ever since I cleared secure boot keys from the BIOS menu I’m getting this lines of output/log dump/whatever it is called on every boot. This shows up right before it enters grub menu.

This is on Fedora 36. I’ve been using secure boot for a while with a wifi driver module key enrolled in the MOK list. This has been my first time handling MOK key enrollment. Yesterday I did a reinstall, just switching out different Spin, but after a clean reinstall I was surprised to find out from “mokutil --list-enrolled” that the MOK key from previous installation was still there. So I ran “mokutil --export” so that I can remove it from the MOK list, but it gave me “MokListRT is empty” and no key was exported. At that time I didn’t know about “mokutil --reset” and I remembered that there’s an option to clear secure boot keys on the BIOS menu itself. Ever since I did that I keep getting this lines talking about mok.c just before the grub menu. It’s pretty long but it goes away very quickly.

Here is the video.

Sorry if it’s hard to see with all the white smearing on my screen.

Also now everytime I boot without secure boot enabled I also get this “secure boot is not enabled” screen.

Based on what I can read from that dump it seems like there’s no error. I can boot into Fedora just fine, but I’m worried that it will be an issue later because so far I still can’t export any MOK key. Even after I did “mokutil --reset”, where it finally removed my akmods key from MOK list, I still get “MokListRT is empty” message.

You may have wiped out all secure boot keys, To check, run

 mokutil --pk
 mokutil --kek
 mokutil --db
 mokutil --dbx

They should contain the keys that came with the system. If you are lucky, bios might be able to restore them to factiory default.

Yeah, there’s an option to load HP default secure boot keys on BIOS too, but that I already did right after I cleared the SB keys from BIOS.

I ran them all and they all seem like how they were when my secure boot was still normal.

Oh, this is new. I just ran into this too just now right after choosing my live Fedora on grub.

So it’s happening right before and after the grub menu. Though, this one has an error right at the end, but I’m not sure what is it referring to.

I would have expected some more entries in dbx. I am not sure that the all zeroes entry is even valid.

The UEFI bios would not touch the MOK list anyway, as that is fo=r shim only.

Ok, so I figured it out. The problem was that I ran “mokutil —set-verbosity true” just before I went into the BIOS menu to clear up the keys. I only needed to set it to false and now it boots normally, it also no longer complains when I boot without secure boot enabled.

I thought —set-verbosity would help me solve the “MokListRT is empty” issue with more verbose command output. Sorry, I didn’t have bash history to backtrack through because I reinstalled Fedora a couple of times since then.

I really appreciate the reply, though, thank you!
