Symptom & Impact

Ports package builds fail, delaying release and patch delivery pipelines.

Environment & Reproduction

Likely after upgrading base jail but not refreshing ports tree metadata.

Root Cause Analysis

Build environment components target incompatible branches or ABI levels.

Quick Triage

List active jail and tree mappings for affected build set.

Step-by-Step Diagnosis

Review poudriere logs to isolate first dependency or ABI mismatch.

Solution – Primary Fix

Recreate or update jail/tree pair and rebuild package set coherently.

Solution – Alternative Approaches

Use quarterly branch pinning to reduce churn in build farm.

Verification & Acceptance Criteria

Target package list builds cleanly with reproducible artifacts.

Rollback Plan

Switch to last successful package repository if build break persists.

Prevention & Hardening

Automate jail and tree freshness checks before scheduled builds.

Related Errors & Cross-Refs

Often paired with distfile mirror failures and flaky network pulls.
