Grub 2:2.06.r322.gd9b4638c5-1 won't boot and goes straight to the BIOS after update

An OT reminder sometimes seems neccesary, again, and again…

So, who’s going to open up a new thread in PUB for such chit-chat about things that should or shouldn’t be, surrounding this grub-issue or related matters, since it seems to be always tempting to many (including myself), to engage in?

(I just did it.)
