This error is not a result of SecureBoot being supported or not. Why is shim unable to write to an nvram variable at runtime? That looks like a problem with the firmware's UEFI implementation.

I believe we also should only be setting MokListRT, if MokList is also set. Were you prompted to enroll a MOK key on this system (unfriendly blue screen), and did you do so?

The most likely cause for Ubuntu to prompt to you to enroll MOK is if you have nvidia driver packages installed; but your bug report shows that you are using nouveau drivers and there is no nvidia kernel module loaded. Did you previously try to install the nvidia binary drivers?
