This bug was fixed in the package shim-signed - 1.27~16.04.1

---------------
shim-signed (1.27~16.04.1) xenial; urgency=medium

  * Backport shim 0.9+1474479173.6c180c6-1ubuntu1 to 16.04. (LP:
#1637290)

shim-signed (1.27) zesty; urgency=medium

  [ Steve Langasek ]
  * Update to the signed 0.9+1474479173.6c180c6-1ubuntu1 binary from
    Microsoft.
  * update-secureboot-policy:
    - detect when we have no debconf prompting and error out instead of ending
      up in an infinite loop.  LP: #1673817.
    - refactor to make the code easier to follow.
    - remove a confusing boolean that would always re-prompt on a request to
      --enable, but not on a request to --disable.

  [ Mathieu Trudel-Lapierre ]
  * update-secureboot-policy:
    - some more fixes to properly handle non-interactive mode. (LP: #1673817)

shim-signed (1.23) zesty; urgency=medium

  * debian/control: bump the Depends on grub2-common since that's needed to
    install with the new updated EFI binaries filenames.

shim-signed (1.22) yakkety; urgency=medium

  * Update to the signed 0.9+1474479173.6c180c6-0ubuntu1 binary from Microsoft.
    (LP: #1581299)
  * Update paths now that the shim binary has been renamed to include the
    target architecture.
  * debian/shim-signed.postinst: clean up old MokManager.efi from EFI/ubuntu;
    since it's being replaced by mm$arch.efi.

Bug description:
  [Impact]
  We might want to boot securely one of these days.

  [Test case]
  1) Upgrading
  - Update to new shim, shim-signed, grub2, grub2-signed on an UEFI system.
  - Verify that the new shimx64.efi file is under /boot/efi/EFI/ubuntu, along with mmx64.efi and fbx64.efi.
  - Verify that /boot/efi/EFI/ubuntu/MokManager.efi no longer exists.
  - Verify that trying to apt install grub alone, or apt install shim alone, pulls in the correct matching versions of packages and gives the same results.

  2) Booting normally
  - Update to new shim, shim-signed, grub2, grub2-signed on an UEFI system, with Secure Boot enabled.
  - Verify it boots successfully to the login prompt.
  - There should be no messages about "Verification failure" or other errors before the kernel is loaded.

  3) Network boot.
  - Update to shim signed and grub2 signed EFI binaries on the TFTP server used.
  - Verify that a network booting system still boots normally through shim and grub, reaching a login prompt.

  4) BootEntry options
  - Update to new shim, shim-signed, grub2, grub2-signed on an UEFI system.
  - Update or install fwupdate.
  - Verify that new updates can be applied via fwupdate, that when an update is available, fwupdate will correctly start, apply the update, and reboot to shim normally, leading to a working system.

  5) live builds
  - confirm that the new version of livecd-rootfs has been published to -updates first, and that a daily build of the UEFI-enabled cloud images succeeds with the new shim filenames.

  [Regression Potential]
  Any failure to load the kernel from grub, or for shim to load grub, or for the system firmware to load shim (such as "Verification failure" messages) or failure to retrieve or parse BootEntry extended options (such as necessary to load MokManager or fwupdate) should be considered regressions.
