Hey Adam,
Thanks for using WireGuard. See my response below.

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 good news is that I can report that I was able to build, install and
run Wireguard on CoreOs.
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

Are you running into this issue on a freshly provisioned server? Or
after you do a system update? Do you reboot into the most current kernel
if you do update? Does the kernel update along with kernel-devel and
kernel-headers?
This issue is caused by you running a kernel that doesn't have the
correct kernel-header package installed:
[root@localhost ~]# dkms status
wireguard, 0.0.20170726: added
[root@localhost wireguard-0.0.20170726]# dkms build -m wireguard -v
0.0.20170726
Error! echo
Your kernel headers for kernel 4.11.8-300.fc26.x86_64 cannot be found at
/lib/modules/4.11.8-300.fc26.x86_64/build or
/lib/modules/4.11.8-300.fc26.x86_64/source.
[root@localhost ~]# uname -a

[root@localhost ~]# rpm -qa |grep kernel

kernel-core-4.11.8-300.fc26.x86_64
kernel-headers-4.11.11-300.fc26.x86_64
I just tested the latest package on Vagrant and it works after running a
dnf update and rebooting into the most current kernel that matches the
currently installed kernel headers package.

You either want to install the kernel-headers package that matches your
currently running kernel or dnf update and reboot, then DKMS will auto
build the WireGuard kernel module on boot.
