Neutron doest start - Error: No type driver for tenant network_type: local

[Dalton Cézane]

I am using this guide https://docs.openstack.org/neutron/queens/install/ to install Neutron on an Ubuntu 18.04 VM. I carried out all the steps in the following link: https://docs.openstack.org/neutron/queens/install/controller-install-option1-ubuntu.html . Then, in the final steps to restart the services (https://docs.openstack.org/neutron/queens/install/controller-install-ubuntu.html), I am facing problems.

Here is the log:
2021-01-28 11:47:11.420 25612 ERROR neutron.plugins.ml2.managers [-] No type driver for tenant network_type: local.

The link https://docs.openstack.org/neutron/queens/install/controller-install-option1-ubuntu.html tells to configure type_drivers of the ML2 plugin (/etc/neutron/plugins/ml2/ml2_conf.ini) as:

[ml2]
# ...
type_drivers = flat,vlan

I was just able to solve the problem when added the "local" to the type_drivers options. I think the documentation should be updated.
