Os-prober is now segfaulting - can't boot Windows

Support

After the latest updates from stable Manjaro started booting immediately without giving me the usual menu… Anyone else dual booting and having issues?

Attempting to run os-prober manually gives me:

    ~  sudo os-prober                                                                                                                                          ✔

Seems somehow related to: [Workaround]os-prober segmentation fault. GRUB new update mess! / Newbie Corner / Arch Linux Forums but I’m pretty sure we’re already on 2.12 here?

grub 2:2.12.r226.g56ccc5ed-1

It looks like grub has been rolled back to version 2.2.12-3 in the repos:

mbn info grub -q | grep -e 'Branch' -e 'Version' -e 'Build Date'
Branch         : archlinux
Version        : 2:2.12.r226.g56ccc5ed-1
Build Date     : Thu 27 Feb 2025 18:47:35 
Branch         : unstable
Version        : 2:2.12-3
Build Date     : Fri 04 Oct 2024 19:22:36 
Branch         : testing
Version        : 2:2.12-3
Build Date     : Fri 04 Oct 2024 19:22:36 
Branch         : stable
Version        : 2:2.12-3
Build Date     : Fri 04 Oct 2024 19:22:36

mbn can be found in the manjaro-check-repos package

Try doing a downgrade to see if the older version of grub fixes the issue:

sudo pacman -Syuu

Yeah that seemed to do it! Thanks, guess someone pushed something with bugs? :smiley:

There were problems with grub caught in the testing branch update, so it was rolled back.

Branch compare for Manjaro - grub

guess someone pushed something with bugs?
