Please run 'apport-collect 1518018' from the affected system.

The most likely explanation of this behavior is that the -signed
packages (grub-efi-amd64-signed, shim-signed) have accidentally become
uninstalled from your system, possibly due to a wrong apt sources
configuration that pulled inconsistent packages from -proposed; this
would leave you with only the unsigned packages installed, which the
upgrade would then try to write as your bootloader despite being
incompatible with SecureBoot.

It may be a good idea for us to check the presence of signed bootloaders
+ secureboot on upgrade and warn/fail if we are trying to install an
unsigned bootloader; yours would not be the first report of boot
problems resulting from uninstalling the secureboot bootloader package.

Title:
  Secure boot fails after upgrade to 15.10

Status in shim package in Ubuntu:
  Incomplete

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
