[Bug 978464] Re: Upgrade 10.04 to 12.04 Beta 2 failed, grub issue

[Seiichi Horie]

Hi

I have upgraded from 10.04 LTS to 12.04 by update-manager. And had same
problem. This problem is able to reproduce 100% on my VMware Workstation
8.0.3.

By using Super Grub2 Disk, I could start the upgraded 12.04 and install-
grub command could fix this.

I will upload my /var/log/dist-upgrade

Title:
  Upgrade 10.04 to 12.04 Beta 2 failed, grub issue

Status in “grub2” package in Ubuntu:
  Confirmed

Bug description:
  I upgraded a 10.04 to 12.04 Beta 2.

  After the compulsory reboot, I ended up stuck on a GRUB shell.

  GRUB didn't get properly updated

  Screen shot is attached.

  I know how to pass that problem manually by upgrading grub
  configuration by hand using a LiveCD.. But obviously, for your lambda
  users it's going to be a massive blocker.
