When installing a Pi-Hole on an Ubuntu server I found that once install the Ubuntu server itself was no longer able to resolve DNS.

I wasn’t sure how to resolve this until I was researching LAN Cache and they highlight a similar issue and how to “resolve” it.

If your cache host is running a recent Linux distribution, it is likely running systemd-resolved, which listens on port 53. If you want your cache host to bind to 0.0.0.0:53 (INADDR_ANY, all IPv4 addresses), you will first need to disable systemd-resolved’s stub listener.
