I've been impressed with Wireguard, its design has helped simplify the implementation of a distributed sandbox app I am building quite a bit. But I have had mixed results getting it running on different distributions.

The bad news is I was unable to get Wireguard working on either CentOS 7, Fedora 26 or Fedora 25 (running these on AWS), it doesn't appear to be installing the kernel module properly. 

Here's what I see when install the RPM:

+ dkms add -m wireguard -v 0.0.20170629 -q --rpm_safe_upgrade

+ dkms build -m wireguard -v 0.0.20170629 -q

+ dkms install -m wireguard -v 0.0.20170629 -q

D: %post(wireguard-dkms-1:0.0.20170629-2.fc25.noarch): waitpid(14760) rc 14760 status 100

warning: %post(wireguard-dkms-1:0.0.20170629-2.fc25.noarch) scriptlet failed, exit status 1

Non-fatal POSTIN scriptlet failure in rpm package wireguard-dkms

Looks like it might have worked:

[fedora@ip-1~]$ sudo dkms status 

wireguard, 0.0.20170629: added

BUT:

[fedora@ip-1 ~]$ sudo ip link add dev wg0 type wireguard

I tried this on the latest version of the RPM and this earlier version. I also tried compiling it from source on Fedora but make failed early on.  

I disabled selinux, verified the kernel config is good and manually enabled udp_tunnel for good measure. Any other suggestions? (I did see an earlier post here recommending using kernel-ml for centos 7 but I need to use the Atomic Host variant and swapping out the kernel on that is non-trivial. I was hoping using a recent Fedora would solve the kernel compatibility issues.)

thank you!
