In attempting to follow the installation instructions, I encountered errors from missing Stouts.postfix and openwisp.influxdb roles. This caused the playbook to fail.
I was able to workaround the issue by manually installing them.
Create a subfolder in the openwisp2-ansible-playbook folder called "roles".
Switch into the newly created "roles" folder.
Run git clone https://github.com/openwisp/ansible-ow-influxdb
Rename the folder ansible-ow-influxdb" to "openwisp.influxdb
Run git clone https://github.com/Stouts/Stouts.postfix
Then switch back to the openwisp2-ansible-playbook folder and run the playbook per the installation instructions.
