Tip on installing NSD on Ubuntu 18.04
With Ubuntu LTS 18.04 if you are installing NSD, you may find it helpful to disable systemd-resolved as this daemon will cause port conflicts with port 53.

Thanks for the tip! If you want to run both NSD and systemd-resolved, you can also configure systemd-resolved to prevent it from binding to port 53 by adding or editing the following line in /etc/systemd/resolved.conf:
DNSStubListener=no
Then, restart systemd-resolved and nsd with the following commands:
sudo systemctl restart systemd.resolved
sudo systemctl restart nsd
