Fails on 18.04

[interstar]

Tried to create the docker container and I get an error that I need Python 3.6

So I moved to starting from Ubuntu 18.04, had to add "sudo" as part of the install list.

But something in the node installation says it won't work with bionic

+ curl -sLf -o /dev/null 'https://deb.nodesource.com/node_7.x/dists/bionic/Release'
