Ansible and Trellis are currently compatible with Python 2 only (Python 3 compat likely mid 2018).

> `Failed to validate the SSL certificate for...` errors are very often connectivity issues that resolve themselves if you try later ([example](https://discourse.roots.io/t/task-wp-cli-install-wp-cli-tab-completions/5708/7)), maybe 30-60 minutes later. Sometimes you can regain connectivity faster by changing your IP (enable a VPN, go to a coffee shop, etc.).

Could also search discourse for the error output snippet `Make sure your managed systems have a valid CA certificate installed.`
