Title:
  update-grub does not work anymore

Status in grub2 package in Ubuntu:
  Expired

Bug description:
  Binary package hint: grub2

  One of the later updates delivers an invalid grub-probe.
  Output of
  sudo grub-probe /dev/sda 
  is
  grub-probe: info: cannot open `/boot/grub/device.map'.
  grub-probe: info: changing current directory to /dev.
  grub-probe: info: changing current directory to dri.

  grub-probe: error: cannot find a device for /dev/sda (is /dev mounted?).

  And output of lls -l /dev/sda
  is
  brw-rw---- 1 root disk 8, 0 2010-08-12 12:40 /dev/sda

  Subsequently - update-grub and others down the line do not work which
  e.g. results in Nvidia drivers not being integrated which then crashes
  Xorg.
