[Bug 1769044] Re: Ubunut 18.04 d-i preseeded installer hangs at 66 % of update-grub...

Affecting Dell DSS1500, 100% of the time.  SATA drive.  Workaround
(found elsewhere) is to ctrl-alt-f2 during the hang and "ps | grep dm"
and kill the pid running "dmsetup create -r osprober-linux-sda1".
Install will then finish, but this doesn't scale when provisioning 20
servers at once (as I am).

Title:
  Ubunut 18.04 d-i preseeded installer hangs at 66 % of update-grub...

Status in debian-installer package in Ubuntu:
  Confirmed

Bug description:
  Checking alt-f4, I can see stuff about os-prober, going alt-f2, ps |
  grep mounted; then killing the first process, it goes further and all
  is fine.

  Annoying thing, out of 60 machines it happened on 50, why, I can't
  tell yet.
