Hi - I hope someone can help as I'm not really familiar with ansible. When
I try to install OpenWISP2 on a Raspberry Pi 3 (Rasbian stretch 4.14.79)
using the following command
ansible-playbook -i hosts playbook.yml -u pi -k --become -K
everything runs normal until the "pip install django-redis" command (see
below). I tried to manually install django-redis from the commandline, but
this didn't help (as I guess ansible works in its own environment). It
looks like the ansible environment simply misses some ssl certs to validate
the https connection to the repository, but I don't know how to fix. Any
ideas?
