Title:
  double free error when secure boot is enabled

Status in grub2 package in Ubuntu:
  Fix Released

Bug description:
  I just did an upgrade and rebooted, and upon loading the kernel grub
  presented me with a "double free" error. It was doing this no matter
  what kernel I tried to boot, including kernels which were booting fine
  before. Out of desperation I disabled secure boot in the bios and the
  kernel loaded and booted without error. When I turned secure boot back
  on the error came back.

  It's likely that none of kernels I have installed have a valid
  signature, since I generally install test builds before uploading
  kernels, so maybe that's related.
