wireguard: module verification failed

[Ronan Lucio]

Hi,

I just installed wireguard on two Ubuntu-18.04 instances and I'm
getting the error message below:
"wireguard: module verification failed: signature and/or required key
missing - tainting kernel"

Some research about this error say I need to recompile the system kernel.
Is that right?
Is there anything else I can do?

Thank you

Yikes. Not a very nice situation, but of course it's temporary, as the
problem will disappear once we merge to mainline.

Here is what I found in dmesg:

you have to add the driver to kernel sources and build the whole kernel 
to not get this warning, is a new policy from kernel
