Thanks for explaining how to trigger an update to reinstall @dejan ! That’s the information I’d been waiting on (sorry Jon, your advice was unhelpful as Arne had just warned us not to use testing).
Unfortunately modifying that text DB file and reinstalling 182 did not fix the problem on my system, it’s still trying to boot EFI for some reason and I can’t get it to boot legacy BIOS without using a boot stick (like Supergrub) and having that load an entry from grub.cfg.
Also now the problem with the console font (or display?) is back. I’ll update the bugzilla ticket. (EDIT: This happened once before but I rebuilt Grub again and it went away, so I removed it from this thread. The thread is just too long sorry)
