Symptom & Impact

dnf cannot find packages because expected RHEL 9 repos are no longer enabled.

Environment & Reproduction

Run `subscription-manager status` and `subscription-manager repos –list-enabled`.

Root Cause Analysis

Ensure `subscription-manager` and `rhsm-certificates` packages are current.

Quick Triage

Check related refresh timers and management agents that may alter repo entitlement state.

Step-by-Step Diagnosis

Inspect `journalctl` and rhsm logs for entitlement refresh or certificate issues.

Solution – Alternative Approaches

Verify access to subscription endpoints through proxies and firewalld egress controls.

Verification & Acceptance Criteria

Check for denials if custom scripts write entitlement files in restricted directories.

Rollback Plan

Refresh registration, reattach subscriptions, and enable required repos with subscription-manager.

Prevention & Hardening

Run `dnf repolist` and confirm package installation works from expected channels.

Monitor repo state drift and pin entitlement policies in lifecycle management.
