[Bug 1479213] Please test proposed package

[Brian Murray]

Hello bugproxy, or anyone else affected,

Accepted grub-installer into trusty-proposed. The package will build now
and be available at https://launchpad.net/ubuntu/+source/grub-
installer/1.78ubuntu20.3 in a few hours, and then in the -proposed
repository.

Please help us by testing this new package.  See
https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to
enable and use -proposed.  Your feedback will aid us getting this update
out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug,
mentioning the version of the package you tested, and change the tag
from verification-needed to verification-done. If it does not fix the
bug for you, please add a comment stating that, and change the tag to
verification-failed.  In either case, details of your testing will help
us make a better decision.

Further information regarding the verification process can be found at
https://wiki.ubuntu.com/QATeam/PerformingSRUVerification .  Thank you in
advance!

Title:
  ISST-SAN: fsp-chip: Alpine: LE-UBUNTU 15.10: LPAR chip01 unable to
  install base OS due to inability to install the GRUB boot loader on
  hard disk

Status in grub-installer package in Ubuntu:
  Fix Released
Status in grub-installer source package in Trusty:
  Fix Committed
Status in grub-installer source package in Vivid:
  Fix Committed

Bug description:
  [Impact]
  Administrators installing Ubuntu on systems with more than 26 hard disks.

  [Test case]
  1) start a Ubuntu Server install on a server with > 26 disks: /dev/sdaa should exist.
  2) Complete the installation

  Without the fix, the installation should fail at the "Install the GRUB boot loader on a hard disk" task.
  With the fix, the installation should complete successfully.

  [Regression Potential]
  This has a low regression potential as it only changes enough of grub-installer to allow matching of disks of the naming scheme /dev/[shv]d[a-z]*, where it was previously only matching for one occurrence of the drive letter ([a-z]). This matching only happens when doing the initial installation of a system; further runs will rely directly on grub-install without trying to match device names.

  We require patches to partman-multipath, parman-base and grub-
  installer packages for Ubuntu 15.10 version to address this
  installation problem.

  These packages have already been updated to Ubuntu Trusty and Ubuntu Vivid.
