Title:
  Boot stuck in UEFI after enrolling keys for drivers

Status in linux package in Ubuntu:
  Incomplete
Status in systemd package in Ubuntu:
  Invalid

Bug description:
  Hello,

  I faced the following problem.
  After the fresh installation of Ubuntu, everything works well. But after I install some drivers (NVidia or VirtualBox) that require key enrolling I stuck on boot. See below detailed description.

  Normal behavior:
  1. Press the power button on Laptop.
  2. Enter to Grub menu, select Ubuntu and continue.
  3. See boot logo.
  4. Successfully boot in Ubuntu.

  Bad behavior:
  1. Install drivers (for example VirtualBox via $ sudo apt-get install virtualbox).
  2. Enter a password for Secure boot during installation.
  3. Shut down the system.
  4. Press the power button on Laptop.
  5. Enter to Grub menu, select Ubuntu and continue.
  6. See boot logo.
  7. System stuck, only black screen and blinking white underscore cursor.

  After some time I realized that to continue boot after step 7 I need the following.
  8. Change console by Alt+Fn+F2.
  9. Return to the original console by Alt+Fn+F1 (after that booting continues immediately).
  10. Successfully boot in Ubuntu.

  Issue occurrence: 100%.
  Removing drivers (apt-get purge virtualbox) doesn't help.
  Disabling of secure boot in BIOS doesn't help.

  Expected behavior: To be able to boot successfully.
  Actual result: Stuck on boot.

  Environment:
  $ lsb_release -rd
  Description: Ubuntu Hirsute Hippo (development branch)
  Release: 21.04
  $ uname -a
  Linux tiptop 5.11.0-16-generic #17-Ubuntu SMP Wed Apr 14 20:12:43 UTC 2021 x86_64 x86_64 x86_64 GNU/Linux

  Please find dmesg attached.

  Any help is appreciated!
