Question on: https://github.com/vsoch/lessons/tree/master/_posts/hpc/2018-07-10-sherlock-jupyter.md#21-jupyter-notebook

After following prompts to enter and verify password, I receive an error message and the step apparently fails. Any idea why this problem occurs and what can be done to fix it?

The error message in question:

If you look at the last line, it’s telling you that you are missing a config for Jupyter notebook. Try running Jupyter interactively on the cluster and learning about the config file and how you can customize it. When you’ve tried, and generated one that seems to work, try this again.
