[Bug 949992] Re: Upgrade from Lucid to Precise results in broken grub configuration

It would be helpful if you were to run apport-collect 949992 from the
system you had the issue with as this should collect the log files in
/var/log/dist-upgrade which will help us debug the issue.  Thanks!

Title:
  Upgrade from Lucid to Precise results in broken grub configuration

Status in “update-manager” package in Ubuntu:
  Incomplete

Bug description:
  Performed update-manager -d upgrade from lucid VM to precise. On
  completion, rebooted, and rather than Precise, I'm confronted with a

  grub>

  prompt.

  Attempted recovery by setting root and loading config, but get
  "unknown command hwmatch" when it tries to load the grub.cfg.

  Manually loading vmlinuz and initrd after setting root only gets me as
  far as a busybox prompt.

  Obviously I can't get to the point where I can run ubuntu-bug in that
  VM, so my ability to get logs is currently limited.

  I'm still attempting recovery of the VM, as it's blocking further
  Ubuntu One upgrade testing that I'm engaged in. I'll add further
  information if/as I find it.
