[bitfolk] Ubuntu 24.04 grub package update issue

Hi, A customer running multiple Ubuntu 24.04 VPSes has reported problems with a recent grub package update which gives this error: grub-install: warning: this GPT partition label contains no BIOS Boot Partition; embedding won't be possible. and then fails to complete the update, leaving dpkg in an unhappy state. This is the first report we have seen of this. I am about to try to replicate it. Is anyone else experiencing it? I have a working theory that grub has become more strict and when it is instal;led on a disk with a GPT (rather than a legacy MBR) it wants to see an actual partition of code type EF02 "BIOS boot partition" rather than simply the 4MiB of empty space we have been leaving at the start of your xvda disk. If that theory is correct then: - It may be tricky to fix for existing VPSes - It's an unfortunate change to introduce during an LTS release (i.e. this worked when 24.04 was released) But for now if you are affected I would just like you to get in touch with me off-list. While this is irritating and possibly awkward to fix, I don't think it will end up as a critical issue as we don't actually need grub installed to boot your VPS, only a grub.cfg that looks correct. It's just that the easiest way to get that is to properly install grub. Thanks, Andy -- https://bitfolk.com/ -- No-nonsense VPS hosting
