Question posted in 
Python version: 3.6.8
NetBox version: 2.9.1
CentOS Linux release 7.8.2003 (Core)
I am installing NetBox following the Documentation step by step:
https://netbox.readthedocs.io/en/stable/installation/3-netbox/
I get stuck when I try to create or delete a superuser.
He creates the User but seems like he fails on the password. If I try to create a superuser it fails, trying to create a superuser afterward with the same name throws out "User already exists".
Error:
(venv) [root@ALTLX548 netbox]# cd /opt/netbox/netbox
(venv) [root@ALTLX548 netbox]# clear
(venv) [root@ALTLX548 netbox]# python3 manage.py createsuperuser
Username (leave blank to use 'root'): admin
Email address:
Password:
Password (again):

Just Quoting my comment here again, so i can mark this Thread as answered.
Check the version of PostgreSQL yum gave you. NetBox requires 9.6 or later. I had to find RPMs of newer version via the PostgreSQL site, and yum localinstall
Check the Redis version on CentOS. The install guide notes version 4 or later is required. Yum repo gave me version 3.
Redis only offer source code :
Found RPMs for later versions here https://pkgs.org/download/redis and did yum localinstall.
I had the same issue. In my case, Redis was deployed from Epel repository which is lower than the required version (at date 10/07/2020, Redis 4.0 or higher is required : enter link description here)
