Fedora/CentOS error: wireguard-dkms-1:0.0.20180420-1.fc28.noarch: erase failed

[Germano Massullo]

I had the same problem, and I followed your guide till

> # rpm -e wireguard-dkms-0.0.20180420-1.fc28.noarch

Then I wanted to use 0.0.20180513-1.fc28 snapshot, so I runned

# dkms autoinstall

but I got errors

Error! Could not locate dkms.conf file.
File: /var/lib/dkms/wireguard/0.0.20180218/source/dkms.conf does not exist.

Concerning installed files:
# dnf list installed | grep wireguard
