I created a new root partition and I am trying run update-grub inside a chroot. I bindmount the following
for i in /dev /dev/pts /proc /sys /run; do sudo mount -B $i /mnt$i; done
And then:
update-grub
/usr/sbin/grub-probe: error: cannot find a device for / (is /dev mounted?)
The error message normally occurs when /proc or /dev are not mounted but, as described above, I believe they were mounted correctly.
Why can't I run update-grub?
