Comment on Podman won't start Pihole with an error saying that it can't bind to port 53, as it is already in use, but nothing is using port 53.

  Yup. I ran # nc -u -l 0.0.0.0 53 to listen on port 53. Then I ran # drill @127.0.0.1 53 archlinux.org in another shell. I saw the request in the listening shell.

    Hmm. Can you run another service like github.com/vhiribarren/docker-echo-server on udp 53? If it fails, can you bind another port, both under and over 1024, with success? That would tell us if it’s something with that image or a system problem.

      See the post for the solution.
