Os-prober has been running for over an hour

So I wanted to downgrade Kernel Linux513 to a lower version Linux510 because there are some inconveniences which I don’t like and are causing problems at my company. So i’ve tested some things and realized that these problems don’t happen on my Main Workstation which is running Linux510.
SO i figured maybe downgrading from 513 to 510 might help. SO ive been installing Linux510 for over an hour now because os-prober is stuck or so i believe. Since its been on:

WARNING: os-prober will be executed to detect bootable partitions.
Its output will be used to detect bootable binaries on them and create new boot entries.

for a while now

Any guesses?

It’s probably stuck, so try hitting Ctrl+C.


solved my looong os-prober phases after updating grub some weeks ago.

I was (still am) with 5.14, thus I don’t know if it’s kernel related.

To mitigate this temporarily disable os-prober

Edit /etc/grub/default and set


Then rerun the grub configurator

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

Then reboot and make sure you hit the grub menu - then navigate advanced options and select the 5.10 kernel.

Uninstall 5.13

sudo pacman -Rns linux513

If you need os-prober (only necessary if you have other operating systems) then enable in grub config (setting the value to false)
