"EFI stub" warning when booting (lemmy.cafe)

A couple of days ago I started getting an error message every time I boot my laptop. It says:

EFI stub: WARNING: Failed to measure data for event 1: 0x800000000000000b

Any idea what caused this / what the issue is / how I can resolve it?

Thank you!

I can't give a proper solution but I have had the same problem for almost a year now and I took this thread's advice and ignore it.. Has something to do with secure boot but I'm not sure I actually understood the problem that is causing it.

Some people report slower boot but that's not the case for me. Everything seems to work fine, I just get the error message so, I dunno, maybe I'll just ignore it as well?

Same. That's why I decided to just ignore it. Tried to look into it a bit but seemed to be an upstream (Ubuntu) issue, though I'm not sure.

I'll look into it some more.

It's Secure Boot related. This might help: https://askubuntu.com/questions/1519290/efi-stub-warning-failed-to-measure-data-for-event-1-0800000000000000b-efi-stu
