=== Wireguard Setup ===

For Debian 10, you need to add the backports repo
  apt install linux-headers-$(uname -r)
  sh -c "echo 'deb http://deb.debian.org/debian buster-backports main contrib non-free' > /etc/apt/sources.list.d/buster-backports.list"
  apt-get update
  
If you are using Proxmox
  apt-get install pve-headers
  
Install Wireguard
  apt-get install wireguard wireguard-dkms
