problems with launch.sh on Ubuntu 16.04

[romanchyla]

Following the tutorial, I had to remove pipefail from launch.sh

also, the open [url] results in Couldn't get a file descriptor referring to the console

But all else worked just fine, the jupyterhub was up and running.

Oh right, on Linux the open command isn't going to work for you. On a Mac, that'll open a browser, but on Linux open(1) assumes that the URL is a local file. Odd error message for it though.

You can work around this by running the docker port commands on their own, unadorned by $( ... ) and copying-and-pasting the result into your browser of choice.
