I have installed Jupyter Notebook on ubuntu 16.04 using pip3. I can execute jupyter notebook command. It opens and shows a list of current path directories.
jupyter notebook
In my opinion, it is a good practice to run Jupyter in a dedicated workbook folder.
$ mkdir jupyter_folder $ jupyter-notebook --notebook-dir jupyter_folder
where 'jupyter_folder' is a folder in my home.
This method work without permission issue.
