Download fails on Ubuntu 14.04

[eHanseJoerg]

The following error was presented on an Ubuntu 14.04 server with Python 2.7.6:

TASK [mariadb-connector-java : download archive] **********************************************************************************************************
fatal: [ehprod]: FAILED! => {"changed": false, "msg": "Failed to validate the SSL certificate for downloads.mariadb.com:443. Make sure your managed systems have a valid CA certificate installed. If the website serving the url uses SNI you need python >= 2.7.9 on your managed machine (the python executable used (/usr/bin/python) is version: 2.7.6 (default, Nov 23 2017, 15:49:48) [GCC 4.8.4]) or you can install the urllib3, pyOpenSSL, ndg-httpsclient, and pyasn1 python modules to perform SNI verification in python >= 2.6. You can use validate_certs=False if you do not need to confirm the servers identity but this is unsafe and not recommended. Paths checked for this platform: /etc/ssl/certs, /etc/pki/ca-trust/extracted/pem, /etc/pki/tls/certs, /usr/share/ca-certificates/cacert.org, /etc/ansible. The exception msg was: [Errno 1] _ssl.c:510: error:14090086:SSL routines:SSL3_GET_SERVER_CERTIFICATE:certificate verify failed."}

Seems like an incompatibility with Python 2.7.6 on the target host. Redefining the host with

ansible_python_interpreter: /usr/bin/python3

makes it work.
