netbox: gunicorn doesn't start on Ubuntu 16.04

I followed the docs and installed everything to the default directories. After installing gunicorn and supervisor, I get ‘502 Bad Gateway’ when I browse to the site.

When looking at ‘service gunicorn status’, I see:

● gunicorn.service
   Loaded: loaded (/etc/init.d/gunicorn; bad; vendor preset: enabled)
   Active: active (exited) since Wed 2016-06-29 20:41:33 MDT; 11min ago

When I try to run the gunicorn -c /opt/netbox/gunicorn_config.py netbox.wsgi command in the /etc/supervisor/conf.d/netbox.conf config file, from the /opt/netbox/netbox/ directory, I get the following:

if I run as sudo, I get this:

I fixed this with the link from @therealjoshuad and running ALL of my “pip” commands as “sudo -H”

I rebuild a new VM with Ubuntu 16.04 and ran through the documentation again. I am having the same exact issue. Anyone else seeing this?

I ran into this issue as well from a fresh Ubuntu 16.04.2 install and using python 3. Gunicorn is trying to run from python2.7

File "/usr/lib/python2.7/dist-packages/gunicorn/util.py", line 366, in import_app
    __import__(module)
  File "/opt/netbox/netbox/netbox/wsgi.py", line 12, in <module>
    from django.core.wsgi import get_wsgi_application

Installing gunicorn (and uwsgi, maybe not required) for python3 fixed the issue for me. Run:sudo -H pip3 install gunicorn uwsgi

@LociNetworks thanks I found the mistake. I install it package at OS level. I remove the package and reinstall while activating the virtual environment I created. Now its fine.

But now I am not able to find the following file at the following path sudo nano /etc/systemd/system/gunicorn.service

setting up django on Linux I am following the steps from the below location, https://gist.github.com/ganmedia/afbada8ff6ff1733e27f7fd818eb34fd
