Hi,
I follow the installation steps from documentation : https://docs.openstack.org/zun-ui/stein/install/index.html. And I have an error when I restart apache2 (I got 500 error).
In apache2's logs, I found this error :
mod_wsgi (pid=38545): Target WSGI script '/usr/share/openstack-dashboard/openstack_dashboard/wsgi.py' cannot be loaded as Python module.
mod_wsgi (pid=38545): Exception occurred processing WSGI script '/usr/share/openstack-dashboard/openstack_dashboard/wsgi.py'.

Also, when i try to execute python3 manage.py compress I have an error :

To solve this error I just execute :
sudo pip3 install -c https://git.openstack.org/cgit/openstack/requirements/plain/upper-constraints.txt?h=stable/stein -r https://raw.githubusercontent.com/openstack/horizon/stable/stein/requirements.txt
Pip change the version of python-novaclient from 16.0.0 to 13.0.2 and I can compress after. But I got the first error after apache2 restart.
