Bluefin stable image 40.20240801.0 fails to boot

There was an update yesterday (thursday), which probably means that it was a security update, given that stable is typically updated on tuesdays.

When I select the newest grup menu entry I get (transcribed):

error: ../../grub_core/kern/efi/sb.c:182 bad shim signature
error: ../../loader/i386/efi/linux.c:258 you need to load the kernel first

And after a few seconds the grub boot menu opens again.

Secure boot is enabled.

This is most likely Secure Boot related. I would disable it, then enter ujust enroll-secure-boot-key in the terminal on the next boot and enter the password universalblue and turn Secure Boot back on, and see if the error still occurs.

That solved it. I’m still new to secure boot and I didn’t know that I also need to run ujust enroll-secure-boot-key after switching secure boot on.
