[Bug 1936759] Re: shim-signed 1.48+15.4-0ubuntu5 does not secure boot

[Julian Andres Klode]

Please also test the shim-signed 1.50+... binaries in proposed.

If they do not work, please run mokutil --set-verbosity true and reboot
and capture the output with a camera such that we can see verbose
logging.

Thank you!

Title:
  shim-signed 1.48+15.4-0ubuntu5 does not secure boot

Status in shim-signed package in Ubuntu:
  Incomplete

Bug description:
  shim-signed package installs with no error with apt upgrade, but then
  the system cannot boot afterwards with secure boot enabled. System
  hangs indefinitely on UEFI manufacturer logo screen (Dell in this
  case), not getting as far as grub. Disabling secure boot is a
  workaround.

  Rolling back to previous shim-signed version 1.46+15.4-0ubuntu1 fixes
  the problem (system can once again boot with secure boot enabled).

  Done this for now to allow secure boot to be enabled:
  $ sudo apt install shim-signed=1.46+15.4-0ubuntu1
  $ sudo apt-mark hold shim-signed

  Details of system where problem is observed:
  - Dell XPS 13 7390 laptop
  - Intel® Core™ i7-10510U CPU / 16GB RAM
  - BIOS/UEFI firmware version: v1.8.0 (latest)
  - Ubuntu hirsute 21.04 64bit (Linux only, single OS, not dual booting)
  - Kernel version: 5.11.0-22-generic
  - GRUB: 2.04-1ubuntu45

  Any questions / additional info, please ask.
