Comment 2 for bug 1858034

Workaround / Possible Fix?

It looks that the /etc/uwsgi/magnum-api.ini is wrong at two positions.

As mentioned above, there is the need to use python3.6 instead of 2.7 so change from:

wsgi-file = /openstack/venvs/magnum-20.0.0/lib/python2.7/site-packages/magnum/api/app.wsgi

to

wsgi-file = /openstack/venvs/magnum-20.0.0/lib/python3.6/site-packages/magnum/api/app.wsgi

In addition the virtualenv is not set correctly. This needs to be changed from:

virtualenv = /openstack/venvs/magnum-20.0.0/bin

to

virtualenv = /openstack/venvs/magnum-20.0.0

At least for me the service is now up and running:
