fixup

On ubuntu you will run into

Error starting userland proxy: listen tcp4 0.0.0.0:53: bind: address already in use.

This can be fixed by:

• vim /etc/systemd/resolved.conf set DNSStubListener=no
• sudo ln -sf /run/systemd/resolve/resolv.conf /etc/resolv.conf
• sudo systemctl restart systemd-resolved
