Yes; the errors in your log are exactly like that one.  The one subtle
difference I just noticed though is that that was dealing with software
raid, but it sounds like you are using bios fakeraid.  I would suggest
not using the bios fakeraid.

Title:
  [Ubuntu 18.04] Failure to install grub on md-disks.

Status in dellserver:
  New
Status in grub2 package in Ubuntu:
  New

Bug description:
  Steps:
  1. Setup a DellEMC 14G PE server with 2 Onboard SATA disks.
  2. Setup a md-raid (RAID1) on these SATA disks through BIOS S140 controller in UEFI mode.
  3. Start installing Ubuntu 18.04 server (debian installer image)
  4. Select default values for all prompts and observe the grub failure in the end.

  Attaching the screenshot and logs.
  Let me know if any more details are required.

  Ubuntu 16.04.4 works fine in the same setup.
  Hence considering this as a regression.
