# ansible-playbook --connection=local  /etc/ansible/install-insights.yml

ERROR! the role 'RedHatInsights.insights-client' was not found in /etc/ansible/roles:/etc/ansible/roles:/usr/share/ansible/roles:/etc/ansible

The error appears to have been in '/etc/ansible/install-insights.yml': line 4, column 5, but may
be elsewhere in the file depending on the exact syntax problem.

The offending line appears to be:

  roles:
  - { role: RedHatInsights.insights-client }
    ^ here

This is because the role is in lowercase:

[root@host redhatinsights.insights-client]# ls /etc/ansible/roles/
redhatinsights.insights-client
