Title:
  I just try to install 18,04 LTS over 17,10. I could'nt install it by
  normal update because 17,10 was buggy, so I use an ISO file. The
  system crash saying something like "can't install Grub2 in /target/ so
  the system  will exit.

Status in grub-installer package in Ubuntu:

Bug description:
  I have 2 disk for dual boot, one for Windows and one for Ubuntu. On 17,10, Grub was installed on the Ubuntu disk.
  As 17,10 could not update the files because the kernel package was corrupted by a bug, I try to reinstall Ubuntu with 18,04 using the option: Install 18,04 over 17,10 and erase 17,10.
  When I will leave this I will loose definitly Ubuntu and I will have to return to Windows after 10 years of Ubuntu use. That's "THE" real big problem.
