Missing dependency 'python3-distutils' for 'nyx' package from deb.torproject.org for bionic

I've obtained Tor from the following source:

deb https://deb.torproject.org/torproject.org bionic main
deb-src https://deb.torproject.org/torproject.org xenial main

However I had to manually install python3-distuils and python3-distutils-extra in order to start Nyx. It would otherwise fail to start saying that it's missing the module distutils.spawn

Ubuntu 18.04.0
