Jupyterhub PermissionError: [Errno 13] Permission denied

[r.m...@plenium.com]

Hello, I am trying to install Jupyterhub on Ubuntu 16.04 using conda with the latest versions. I generated the config file after install but havent changed anything on it. SSL not setup yet. When I run jupyterhub I am getting a Permission denied. Can someone help to resolve this issue. Thanks.

Ran below install commands:

# conda install -c conda-forge jupyterhub

# conda install notebook

# jupyterhub --generate-config -f /etc/jupyterhub/jupyterhub_config.py

root@:/etc/jupyterhub# jupyterhub -f /etc/jupyterhub/jupyterhub_config.py
