Description:
Ansible community package is missing a required dependency python2-crypto. Error below is a result of running ansible before installing. Installing resolves. I'd be happy to fix this myself but I'm not certain if/how to send a PR on a community package.

Additional info:
* package version - 2.0.2.0-1 (No other version tested)

* Result of running ansible after installation.

ERROR! Unexpected Exception: The 'pycrypto>=2.6' distribution was not found and is required by ansible
