# walk through install with all defaults

install fails at grub stage.

I chose defaults for disk setup (lvm) and the chose 'install grub to MBR'.
The error message is:

Install the GRUB boot loader on a hard disk
      Unable to intsal GRUB in /dev/vda5
  Executing 'grub-install /dev/vda5' failed.
This is a fatal error.

In the jenkins automated test at
<>, this error first appears in build 86 on February 19. The test was failing with a different and unrelated error prior to that; it's not clear to me if this is a latent issue that was only exposed once an earlier bug was fixed.

As a first thing to investigate, there in fact was a grub-installer upload on Feb 19. I'll start by checking if it could be "as simple" as that upload breaking things.

Looks like it really is the latest grub-intaller upload that breaks this; reverted. The fix should be available in a few moments.

This bug was fixed in the package grub-installer - 1.78ubuntu26

grub-installer (1.78ubuntu26) vivid; urgency=medium

  * Revert changes from 1.78ubuntu25:
    * grub_probe(): return a single line in BTRFS multi-disk RAID configurations
      - It breaks bootloader install on LVM. (LP: #1427821)
