Thanks for using WireGuard. See my response below.<span class=""><br>

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.<br>
<br>
The good news is that I can report that I was able to build, install and run Wireguard on CoreOs.<br>
<br>
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.<br>
<br>
Here's what I see when install the RPM:<br>
<br>
+ dkms add -m wireguard -v 0.0.20170629 -q --rpm_safe_upgrade<br>
<br>
+ dkms build -m wireguard -v 0.0.20170629 -q<br>
<br>
+ dkms install -m wireguard -v 0.0.20170629 -q<br>
<br>
D: %post(wireguard-dkms-1:0.0.201<wbr>70629-2.fc25.noarch): waitpid(14760) rc 14760 status 100<br>

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?<br>
<br>
This issue is caused by you running a kernel that doesn't have the correct kernel-header package installed:<br>
<br>

<br>
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.<br>

<br>
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.<br>
