[Bug 1811598] [NEW] unable to install GRUB. 18.11 install failed to give 16.04 over-write option

[Michael Azoff]

Public bug reported:

I have a dual boot PC (64 bit)- windows 10 and Ubuntu 16.04. I wish to
upgrade Ubuntu 16.04 to 18.11. I ran a new install of 18.11 from CD and
it failed to install GRUB in any /dev/sda and /dev/sdb option. I really
want the 16.04 GRUB to be updated by 18.11. Thanks Michael
