If anyone else gets this issue, the way I managed to solve the issues was:

sudo apt-get -y install ipython
sudo apt-get -y install python-pip

sudo apt-get update && sudo apt-get install python3-dev python3-pip build-essential libzmq3-dev
sudo pip3 install virtualenv
virtualenv -p $(which python3) myenv
source myenv/bin/activate
sudo pip3 install pyzmq
python3 -c 'import zmq; print(zmq.zmq_version())'

sudo pip3 install --upgrade "ipython[all]"

wget https://oss.sonatype.org/content/repositories/snapshots/com/github/alexarchambault/jupyter/jupyter-scala-cli_2.11.6/0.2.0-SNAPSHOT/jupyter-scala_2.11.6-0.2.0-SNAPSHOT.zip

unzip jupyter-scala_2.11.6-0.2.0-SNAPSHOT.zip

chmod +x jupyter-scala_2.11.6-0.2.0-SNAPSHOT/bin/jupyter-scala

sudo pip3 install jupyter_console

Finally to then run the notebook:

ipython3 notebook

@samthebest Thanks for the report, more an ipython installation issue than a jupyter-scala one, but this kind of things might be worth mentioning in a future update of the documentation of jupyter-scala.
