[Bug 1663645] Re: Installation hangs at 66% "Installing GRUB boot loader"

[totoro]

Hi

Bug still present in 18.04.
I make my install from netboot(http://archive.ubuntu.com/ubuntu/dists/bionic/main/installer-amd64/current/images/netboot/)

os-prober version is 1.72 in the target.

And I use a preseed file: (https://pastebin.com/6jB5xVJT)

After few try and different partition and grub configuration, I have all
the time the same problem.

The solution in the debian (https://bugs.debian.org/cgi-
bin/bugreport.cgi?bug=853187) help to pas the problem, but preseed is to
a automatic install, I don't found a way to override the bug without do
it manually. If you have any idea ?

  Fix Released

Bug description:
  When installing Ubuntu 17.04 (daily image) in ppc64el VM, after
  selecting the LVM guided installation, the installation hangs at 66%

  The same issue occured with Debian few days ago: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=853187
  It appeared the issue came from os-prober: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=853277

  The issue was fixed in os-prober 1.74. I've noticed that is os-prober
  1.73ubuntu4 in the daily image.
