Additional context
Add any other context about the problem here.

Start by triggering a build in OpenShift and inspect the Logs for the centos-appstream and centos-baseos errors shown in the report. Trace the affected Maven, Scala, and Node agents to the configuration producing those repository lookups; done means the agent builds finalize without unknown-repository errors.
