modprobe: ERROR: could not insert 'wl': Key was rejected by service

[rvernica]

Here is what I did:

> rmmod bcma # and add to /etc/modprobe.d/blacklist.conf
# none of the other conflicting modules were loaded
> git clone https://github.com/antoineco/broadcom-wl.git
> git checkout  patch-linux4.7
> dkms add /usr/src/broadcom-wl-6.30.223.271
> dkms status
broadcom-wl, 6.30.223.271: added
> dkms build -m broadcom-wl -v 6.30.223.271

Hey @rvernica 👋 Thanks for the report.

People in the following discussion claim that Fedora enforces that modules are signed before they can be loaded: https://github.com/umlaeute/v4l2loopback/issues/394. A solution was proposed, but maybe it is also possible to disable this security mechanism if it's getting in your way (I'm not sure).

Closing due to inactivity. Also, the issue is related to the operating system's security, and not that particular module.
