GRUB os-prober error

[linuxislife]

Hey,

I ran grub-mkconfig and it shows an error, even though I think it’s probably ok… or is it ?

$ sudo grub-mkconfig -o /boot/grub/grub.cfg

Any idea ?

cheers

Well it seems you are not the only one:

Thanks!!! I did search it the other day, but couldn’t find anything…

[linuxislife]

so I did downgrade for the moment (from pacman cache)

$ yay -U file:///var/cache/pacman/pkg/grub-2:2.12-2-x86_64.pkg.tar.zst

loading packages...
warning: downgrading package grub (2:2.12.r226.g56ccc5ed-1 => 2:2.12-2)
resolving dependencies...
looking for conflicting packages...

Packages (1) grub-2:2.12-2

indeed followed by (in my case)

$ sudo grub-install --target=x86_64-efi --efi-directory=/boot/efi --bootloader-id=EndeavourOS-grub

and

sudo grub-mkconfig -o /boot/grub/grub.cfg

We’ll see if the bug is corrected mainstream (it’s been tracked) before using a workaround (and in my case it would probably be so much more convenient (and clever) to just get rid of os-prober)

Cheers !

I didn’t have this issue updating grub on any of my dual boot hardware. But then again i may have os-prober disabled. Windows is already in my grub menu so no need to find it again.
