problem with whyis tutorial

[kavonrtep]

I am trying to test whyis by following your tutorial on https://tetherless-world.github.io/whyis/tutorial using
The first error I get is in step:
whyis$ python3 manage.py load -i http://orion.tw.rpi.edu/~jimmccusker/dataset.ttl -f turtle
I get:

python3 ../whyis/manage.py load -i http://orion.tw.rpi.edu/~jimmccusker/dataset.ttl -f turtle

During handling of the above exception, another exception occurred:

Second, I am consistently getting when I try to restart apache error:

root@f4314fe986bd:/apps/my_knowledge_graph# service apache2 restart
[FAIL] Restarting Apache httpd web server: apache2 failed!

Third - creating user fails. Documentatation says:Registration is available on the website for users but there is no such option available on web interface, additionaly when I run according manual :
/whyis$ python manage.py createuser -u testuser -p testpassword --roles=admin

I get:

I guess something is missing in documentation?
