This is pretty much like this; https://github.com/patjak/bcwc_pcie/issues/70#issuecomment-214289165

Can you still load and run the module?

Don't know about module signing and its effects to out-of-tree modules.

On my machine loading can-isotp only results in: can_isotp: loading out-of-tree module taints kernel. can: isotp protocol (rev 20170725 alpha)

Closing due to missing feedback.

I am running ubuntu 18.04 and had the same problem, except the SSL error lines were slightly different. Generating a signing key and putting it in the appropriate certs folder then allowed the module to be signed. If you don't create the signing key, the module can be run from the compilation folder, but I don't think installed.
