Public bug reported: It is similar almost the same. But I decide to file a separate report of bugs from
https://bugs.launchpad.net/ubuntu/+source/grub-installer/+bug/1767703 Because it destroy existing grub that was not reported there. And this time I hope the guru will see what informations were correct from my machine. Lubuntu 18.04, Ubuntu 18.04 destroy my existing ubuntu 16.04 installed grub.
