Title:
  Secure boot fails after upgrade to 15.10

Status in linux package in Ubuntu:
  New

Bug description:
  I was previously running XUbuntu 15.04 on my Asus UX303L laptop.

  The configuration is dual boot with windows 8.1.

  I ran the upgrade via the software updater and it proceeded normally.

  Upon reboot, I got a red screen saying that something was wrong with
  secure boot and it had to be fixed in the BIOS.

  In BIOS, I disabled Secure boot and was again able to access XUbuntu.

  I would like to re-enable secure boot, but cannot.

  I am happy to help debugging in any way - I am a qualified computer
  scientist.

  Sincere thanks,
  Bob
