Installing more than one ubuntu systems only let me use the very last to update grub configuration.
Configure the grub to my needs then execute sudo update-grub will work on any system but only is recognized when doing so from the last installed system. Otherwise has no effect even if the upgrade-grub command was successfully finished before.
This behavior was different in former times say around with 14.04./16.04.
At that time when using a custom menu on a multiboot system with the first entry made form /etc/grub.d/10_linux I could do that from any system not only from the last one (it takes effect from the system where I updated grub, so the first menu entry loads this system).
Can anyone confirm that "new" behavior and what is a good solution? Or what I'm doing wrong?
THX for any good advise!
