Public bug reported:
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
