When I install the Ubuntu 19.10 I cannot turn on secure boot when I boot from the USB key which contains the installation medium (because I used grub2 to chain-load the Ubuntu live cd).
After than I cannot load nvidia drivers when the secure boot is turned on in BIOS. This seems to be because the secure boot is off the installer did not go through all the mok generation steps described in How can I install Nvidia drivers on Ubuntu 18.04 with secure boot?. Normally if there is a mok key enrolled, when installing the nvidia drivers it will prompt to give some passwords and next boot will be in mok manager.
I wonder what the steps are now to do shim sign and enable secure boot again with the nvidia drivers.
