The important bit is the '-147' at the end, which is still way out of date, though... > Updating your system is probably the first step to fixing your issue. My guess would be that he actually did update the system, it's just running the old kernel still? I.e., if you install kmod-wireguard from elrepo, that depends on a specific version of the kernel (-348 in the current version), but if you haven't rebooted to actually run that kernel, the module is obviously not going to work... So, erm, Mehdi, have you tried turning it off and back on again? ;) -Toke
