Procedure for Updating Snapshot

[Eddie]

What is the correct procedure for updating WG with a new snapshot.

I'm currently running CentOS 7.4 and previously had installed the 
20180420 snapshot.  Today, I tried to update with the new 20180513 one, 
and it appears to be failing.  The command I used was:  yum update 
--disablerepo=* --enablerepo=jdoss-wireguard wireguard*

This resulted in the following messages:

Running transaction check
Running transaction test
Transaction test succeeded

   wireguard-tools.x86_64 1:0.0.20180513-1.el7.centos

Complete!


However, the extra/wireguard.ko module was not built.

I then realised that I had not stopped the running instance, and so ran:

systemctl stop wg-quick at wg0
yum reinstall --disablerepo=* --enablerepo=jdoss-wireguard wireguard*

This resulted in exactly the same errors and again the 
extra/wireguard.ko module was not built.

What am I doing wrong here.

Cheers.
