Server Fault is a question and answer site for professional system and network administrators. It's 100% free, no registration required.

I Upgraded to Ubuntu12.10, and when grub ran through the upgrade it gave me these errors:

  root@secure:/usr/share/grub# update-grub
  error: unknown LVM metadata header.
  error: unknown LVM metadata header.
  Generating grub.cfg ...
  error: unknown LVM metadata header.
  error: unknown LVM metadata header.
  error: unknown LVM metadata header.
  error: unknown LVM metadata header.
  error: unknown LVM metadata header.
  error: unknown LVM metadata header.
  error: unknown LVM metadata header.
  error: unknown LVM metadata header.
  ...

I haven't rebooted yet, scared that if I do, the pc won't boot correctly.. how do I fix this? Here is a copy of logs that'll be helpful, to see whats going on.. http://pastie.org/4389403

Thanks

You're trying to use a pre-release Linux distribution. You should expect that it will have bugs, crash, destroy all your data, etc. You absolutely should not attempt to install it on your primary computer unless you're actively developing or testing it and you are willing to live with complete data loss on that machine.

If you were actively developing or testing it, you would report bugs on Launchpad.

same issue occurred when I attempted to install kernel 3.5 on the previous install, hoping the upgrade would fix things. –  Bob Smith Aug 5 '12 at 2:21
