Though:
[root@fedora-2gb-nbg1-1 ~]# dkms status
wireguard, 0.0.20190702: added

SOLUTION: Running dnf update or yum update to get an up-to-date kernel and matching headers solves the issue.

OK, the kernel and headers were not the same version:
[root@centos-2gb-nbg1-1 ~]# yum list | grep kernel-headers
kernel-headers.x86_64 3.10.0-957.27.2.el7 @updates
[root@centos-2gb-nbg1-1 ~]# uname -a

Having the same problem on Fedora 29, but my kernel headers and active kernel are the same. It seems to be failing because DKMS can't find the file:
[#] ip link add wg0-client-test type wireguard
Error: Unknown device type.
Unable to access interface: Protocol not supported
[#] ip link delete dev wg0-client-test
Cannot find device "wg0-client-test"
[ben@localhost ~]$
[ben@localhost ~]$ dkms status
Error! Could not locate dkms.conf file.
File: /var/lib/dkms/wireguard/0.0.20190702/source/dkms.conf does not exist.
Looks like it's trying to follow a broken symlink:
[ben@localhost ~]$ ll /var/lib/dkms/wireguard/0.0.20190702/source
lrwxrwxrwx. 1 root root 31 Jul 8 12:18 /var/lib/dkms/wireguard/0.0.20190702/source -> /usr/src/wireguard-0.0.20190702```
the symlink shouldn't be broken tho as the target exists:
```[ben@localhost ~]$ ll /usr/src/wireguard-0.0.20190905/
total 268K
drwxr-xr-x. 6 root root 4.0K Sep 10 09:28 .
drwxr-xr-x. 5 root root 4.0K Sep 10 09:28 ..
-rw-r--r--. 1 root root 11K Sep 9 14:44 allowedips.c
-rw-r--r--. 1 root root 1.8K Sep 9 14:44 allowedips.h
...
I manually removed the broken link and recreated it:
sudo ln -s /usr/src/wireguard-0.0.20190905/ /var/lib/dkms/wireguard/0.0.20190702/source
Now DKMS is happy. I rebuilt the modules:
sudo dkms autoinstall
Checked status:
wireguard, 0.0.20190702, 5.2.11-100.fc29.x86_64, x86_64: built
wireguard, 0.0.20190905, 5.2.11-100.fc29.x86_64, x86_64: installed
And it still doesn't work.
lsmod shows it isn't actually loaded. Loading it fails:
modprobe: ERROR: could not insert 'wireguard': Operation not permitted
No idea why it's failing.

I have similar problem, but get different verbose output from modprobe:
# modprobe -vvv wireguard
modprobe: INFO: custom logging function 0x55cf4e172a20 registered
insmod /lib/modules/5.3.11-300.fc31.x86_64/kernel/net/wireguard.ko.xz
modprobe: INFO: Failed to insert module '/lib/modules/5.3.11-300.fc31.x86_64/kernel/net/wireguard.ko.xz': Operation not permitted
modprobe: ERROR: could not insert 'wireguard': Operation not permitted
modprobe: INFO: context 0x55cf4eb9b4c0 released
Any ideas how to get wireguard module loaded? I removed it and rebuild it without success:
dkms remove -m wireguard -v 0.0.20191012 -k 5.3.11-300.fc31.x86_64
dkms install -m wireguard -v 0.0.20191012
Any help us much appreciated.

Your kernel headers for kernel 3.10.0-1062.12.1.el7.x86_64 cannot be found at
/lib/modules/3.10.0-1062.12.1.el7.x86_64/build or /lib/modules/3.10.0-1062.12.1.el7.x86_64/source.

It broke for me on a dnf upgrade a couple days ago on Fedora 30
uname --kernel-release
5.2.13-200.fc30.x86_64
rpm -q kernel-headers
kernel-headers-5.2.13-200.fc30.x86_64
Did a:
sudo rm -r /var/lib/dkms/wireguard/0.0.20190702
sudo ln -s /usr/src/wireguard-0.0.20190905/ /var/lib/dkms/wireguard/0.0.20190905/source
sudo dkms autoinstall
and it works again.
...though this seems odd:
dkms status
wireguard, 0.0.20190905, 5.2.13-200.fc30.x86_64, x86_64: installed
wireguard, 0.0.20190905, 5.2.7-200.fc30.x86_64, x86_64: installed

Thanks for the feedback guys, although this seems related to Wireguard packaging on Fedora

dnf reinstall wireguard-dkms might help

I added a warning in the script that detects if the machine is running on Fedora or CentOS && wireguard not running and tells the user the command to update its machine. Should be better!

It also doesn't work. CentOS Linux release 7.8.2003 (Core)

@Yakashimoto I was on that kernel version too and I had the same problem. Here is what I did #95 (comment)
@chanyshev thanks for the detailed information. Your output looks good, try to reboot. If it doesn't work paste the output of systemctl status [email protected]

@chanyshev Open /etc/wireguard/wg0.conf and /etc/wireguard/params and check the IP addresses. If you aren't sure, I think you can delete the folder /etc/wireguard and run the script again.

Just wanted to chime in here and say that I resolved this on Amazon Linux 2 by running yum reinstall kernel and then restarted wireguard
from wireguard-install.
