My os-prober is disabled

This is a screenshot of my terminal output today from a dist-upgrade


Notice: Warning: os-prober will not be executed to detect other bootable partitions

Here is a screenshot of my etc/default/grub file.

The last time I posted this I was told os-prober is enabled, the but terminal say not.
Also everyone is complaining about nags, I am not getting one.
I am running 22.04.3 with kernel 5.15.0-92-generic (x86_64)

So is os-prober enabled or not?

It is just a warning ... os-prober is insecure since it is using grub-mount to mount/check other OS. The problem is that it mounts other partitions as root so this can be exploited.

I am aware of that. I had an original post about doing a dualboot with windows that I closed when everyone assured me os-prober was not disabled so Iam still confused.

The big question is it disabled on the .iso when you try to install it along side windows so it won't find windows?

No, nor /usr/bin/os-prober nor /etc/grub.d/30_os-prober executable script is disabled per se because It is /etc/grub.d/30_os-prober who emits "os-prober will not be executed to detect other..." warning.

Yes, os probing is not performed until GRUB_DISABLE_OS_PROBER=false line is added to /etc/default/grub.

Yes, that is really interesting question...

@jymm, do you ask because you've experienced something like the undermentioned?

If so, I'd appreciate a confirmation, since that corroboration means that I can confirm that it's a cross-OS problem.

No I have not experienced that. But what I have found from reading is the installation media will find other OS's. Otherwise it couldn't ask the questions it does like 'install along side' or 'overwrite'.

I think you have to permenantly re-enable os-prober on your first boot, update grub and then reboot. Otherwise I think your won't be able to boot into Windows, or even another existing Linux OS.

I have not tried it yet. I know Windows also causes Linux some other unrelated boot problems.

I would say if you are going to try a dual boot you should back up well, download your Windows OS from MS and burn it to an installation media in case things go wrong.
