[Bug 880766] Re: ubiquity and grub-install: fails to install grub on software RAID

[Andrew Cranwell]

Finally found the solution, which leaves me with a question.

Having successfully installed an 11.10 server with RAID, I tried again
on 11.10 desktop: this time, after getting the message that GRUB had not
installed, I chrooted into /target/, did 'sudo-apt-get install mdadm',
then 'sudo grub-install /dev/sda'. No errors.

So the Ubuntu graphical installer (Ubiquity? or whatever underlying
package is responsible) is not installing mdadm into the target
installation, and consequently GRUB can't be installed.

Which package should this bug be filed against?

Title:
  ubiquity and grub-install: fails to install grub on software RAID

Status in GRand Unified Bootloader:
  New
Status in “grub-installer” package in Ubuntu:
  Confirmed
Status in “grub2” package in Ubuntu:
  Confirmed

Bug description:
  Installing from a Mythbuntu amd64 CD booted in UEFI mode. Manually
  created partitions using gdisk, created RAID1 using mdadm. Ran
  Ubiquity installer to create /dev/md0p1 as ext4, install proceeded
  until aborting at the end saying that grub-efi could not be installed.

  Manual attempts to install grub also failed (both from the CD and
  chroot), so the problem package may actually be grub2.
