Troubleshooting an Extension Update That Fails in the Laboratory

Troubleshooting an Extension Update That Fails in the Laboratory starts by identifying which QCUL stage or safety gate is actually failing; the fix should address that layer rather than bypassing the protection.

Likely causes

  • Joomla Installer may report an extension-specific error.
  • The package may install but target-version or route/evidence checks may fail.

Troubleshooting procedure

  1. Open View Problems/Issue Report when available.
  2. Read installer output and log evidence.
  3. Use Undo Lab Update if the restore point is valid.
  4. Correct the extension/site problem and retest; do not push a failed rehearsal.

Verify before production

After resolving Troubleshooting an Extension Update That Fails in the Laboratory, the selected update should return to a clear testable/completed state with exact package/version evidence. Open the lab and report again; do not proceed to production while the test remains failed, ambiguous, or based on a damaged/stale laboratory state.

Capture evidence before changing more things

While troubleshooting Troubleshooting an Extension Update That Fails in the Laboratory, preserve the exact displayed state/error and relevant report/task/log evidence before reinstalling, refreshing, removing, or manually editing data. QCUL’s state machine is designed to make failed work diagnosable; changing several layers at once can erase the evidence that identifies the real cause.
