Latest grub bricked my system (grub_is_shim_lock_enabled not found)

It did last time. That it can break after an update is the entire point of the previous, long discussion: Full transparency on the GRUB issue - Updated 2022-08-29

Personally, I upgraded as usual, did not run grub-install or -mkconfig, (I never did) and… brick. Fortunately on my disposable laptop, again. And another time in a VM.

Right. If glibc updates I expect it’ll break then. Fantastic.
