Module verification failed, module removed

[lordbah]

Description
When the wireguard package is started, the module fails to verify and is removed.

Steps to reproduce

Installed WireGuard-geminilake-1.0.20220627.spk (there was not a dialog box regarding a missing digital signature) and rebooted.

My first attempt to build this failed, looked like something about being unable to resolve cr.sh, whatever that might be. Tried again a few days later, without changing anything I know of, and it succeeded. Loaded that, and it still fails verification, but the module does not get removed. I have yet to be able to test it in operation.
BTW the command at the bottom of https://hub.docker.com/r/blackvoidclub/synobuild72 you need to add "blackvoidclub/" in front of "synobuild72".
