[Bug 439784] Re: Error: Invalid environment block

[A. Eibach]

hah.

Maybe this is not a "bug" after all...

Got this as well, and ended up at this LP bug...BUT...there was
something peculiar.

$ head -1 /boot/grubenv

did NOT cleanly display "GRUB Environment Block" but had a few characters garbled in that line.
I remember this from IDE times, with badly-seated cables that don't display MAXTOR but MBYUIPR or whatever on HDD detection. That's because one single bit is off due to one bent pin.
It hasn't happened too rarely that I only saw a skew cable connection when using a magnifiier, or, at least a good lighting source (which is not always given)

So thanks everybody for the "fix", but I can't blame grub2 for it yet.
See above output ($ head....)

Title:
  Error: Invalid environment block

Status in grub2 package in Ubuntu:
  Confirmed

Bug description:
  Binary package hint: grub2

  grub gave this  error  invalid: environment block when after an unclean shutdown.
  I ended up deleting grubenv and that worked to get me booting again but next time unclean shutdown it boots up and runs fsck? shows some inode stuff and next boot i get the message again.

  Looking at grubenv: it is showing it to be 0 bytes , when this problem
  occurs.

  I also have copied grubenv a read only file from a good computer really has same effect as deleting it.
  Reinstall grub still same problem.

  Running x64 karmic all updates
  In anycase this errormessege while may show there's some bigger issue should not stop me from booting, should it?
