It has been very difficult for me trying to deploy to aws EC2 ubuntu server SINCE I'm coming from windows background. I encounter an error while trying to bind django application to gunicorn. The command I'm running is sudo gunicorn --bind 0.0.0.0:8000 logistics.wsgi:application And the error log is show below:

The reason why I added --user at the end is that running pip3 install gunicorn within the activated virtual enviroment is throwing back permission error as shown below:
