[Bug 1311247] Re: [Grubenv] error: malformed file, press any key to continue

[msth67]

Follow up to my comment #69 : what is triggering the random "READ ERROR"
message is apparently rebooting the system:cold boot does now (kinda)
work with a separate boot partition and the workaround from comment #53
to hide the error message,however attempting to reboot the system often
triggers this other  "READ ERROR" message for which I've found no other
solution than hard reset (power off) the computer and then booting it
again.

Title:
  [Grubenv] error: malformed file, press any key to continue

Status in GRand Unified Bootloader:
  Unknown
Status in “grub2” package in Ubuntu:
  Confirmed

Bug description:
  I have just upgraded from 12.04 to 14.04

  Since the upgrade, when I boot up, the process stops and the normal
  grub screen is replaced after a short while by a message saying

  "error: malformed file, press any key to continue"

  Pressing a key allows booting to continue.

  Someone else who experienced this found that the problem went away
  after having re-installed grub.  I tried this but this did not resolve
  the problem for me.

  synaptic reports the grub package as 2.02~beta2-9
