Public bug reported: I was upgrading from 16.04 to 18.04. The main reason for upgrade is constant problems with WI-FI in 16.04.
I have a UEFI system, hence, in my view, GRUB is not required. However, Ubuntu installs GRUB by default. I had the GRUB installed from 16.04. I had tried removing the GRUB using CMD commands before trying to install 18.04. However, when I rebooted the system, GRUB greeted me to 16.04. I started 18.04 installation as an upgrade to 16.04. The installer failed to install GRUB.
