I attach here a little section from the output on an update. I wonder why it happens - and how to remove it. No urgency, I can't see that it causes any problems - but my OCD gets triggered by error messages
Found 5 snapshot(s)
Found memtest86+ image: /boot/memtest86+/memtest.bin
/usr/bin/grub-probe: warning: unknown device type nvme0n1.
done
The odd thing is I have no idea why something called grub-probe is even running when os-prober is disabled (in /etc/default/grub) because it isn't needed. I was hoping grub-probe was a script, but apparently not - so...
Thanks if someone can answer (with minimum effort!) with a pointer in the right direction.
