Disable Systemd DNS resolver

I ran into an issue recently where I tracked back that the systemd resolver was trying to be a tad to helpful and causing me pain through DNS. So I set out to kill and keep it disabled across reboots. In some quick googling I found a good answer on askubuntu.com.

Regurgitating what the answer is for my reference later and for anyone to find. (Along with a reference link below)

1. Disable systemd-resolvd service:

   sudo systemctl disable systemd-resolved.service
   sudo systemctl disable systemd-resolved-update-resolvconf.service
   sudo service systemd-resolved stop
   

2. If file exists, add to “[main]” section in /etc/NetworkManager/NetworkManager.conf

    dns=default
   

3. Delete symlink and replace /etc/resolv.conf
4. Restart network-manager

    sudo service network-manager restart
