Error installing erpnext on centos 7 - help

I have no bare install instance to for eg look into this error you get:

ASK [mariadb : include] *******************************************************
fatal: [localhost]: FAILED! => {“failed”: true, “reason”: “Unable to retrieve file contents\nCould not find or access ‘/tmp/.bench/playbooks/prerequisites/mysql_secure_installation.yml’”}
to retry, use: --limit @/tmp/.bench/playbooks/production/install.retry

A forum search for eg ‘ansible playbook’ gives recent posts that may give you clues or pointers
