Symptom & Impact

pkg update fails with signature verification errors, blocking package patching.

Environment & Reproduction

Seen after mirror key changes or stale package metadata on FreeBSD 13.

Root Cause Analysis

Repository trust fingerprints, CA store state, or cached metadata are inconsistent.

Quick Triage

Validate repository URLs, DNS reachability, and certificate trust chain.

Step-by-Step Diagnosis

Collect verbose pkg debug output and verify key files under /usr/share/keys/pkg.

Solution – Primary Fix

Rehash certs, clear pkg cache, force bootstrap, then refresh repositories.

Solution – Alternative Approaches

Temporarily switch to the quarterly branch or another trusted mirror endpoint.

Verification & Acceptance Criteria

pkg update and pkg upgrade complete with no signature or TLS warnings.

Rollback Plan

Revert repository override files and restore previous known-good configuration.

Prevention & Hardening

Pin approved repository settings and monitor trust-store drift in automation.

Related Errors & Cross-Refs

Related to DNS failures, TLS interception, and stale manifest cache problems.
