Doc Type:	Bug Fix
Doc Text:	Cause: An ansible release introduced a regression that caused datastructures to fail to serialize when writing them out to a YAML document. Consequence: Users would trigger the regression during the pre-run fact fetching, causing their installation to crash. Fix: Ansible introduced a new YAML serializing system in an update. The old serializing system was replaced with the new one, "AnsibleDumper". Result: The quick installer can run the "Gathering information from hosts" actions now without triggering the error during serializing.
