Title:
  Unable to install Ubuntu 18.04 LTS using Multisystem LiveUSB

Status in ubiquity package in Ubuntu:
  Won't Fix

Bug description:
  I am able to boot into Ubuntu 18.04 LTS from a Live USB, without
  issue, having created it from Multisystem. When I try and install it,
  having selected a partition to format and install to, it constantly
  complains that it can't unmount isodevice and so can't continue.

  If I format the partition in Gparted and try and continue the
  installer, it pops up with that same dialog once and then continues. I
  fill in my information and on the next page I can see that it's not
  actually installing and stuck on "Detecting file systems".
