Symptom & Impact

pkg update stops with signature verification errors, preventing security patches from being installed.

Environment & Reproduction

Typically appears after mirror rotation, stale cache, or interrupted repository sync.

sudo pkg update -f

Root Cause Analysis

Local repository metadata does not match the currently signed remote repository state.

Quick Triage

Confirm DNS, TLS, and time synchronization before deeper package troubleshooting.

date && drill pkg.freebsd.org

Step-by-Step Diagnosis

Inspect repository configuration and verify active mirrors and fingerprints.

cat /etc/pkg/FreeBSD.conf

Solution – Primary Fix

Clear pkg cache and force metadata refresh from trusted mirrors.

sudo pkg clean -a -y && sudo rm -rf /var/db/pkg/repo-* && sudo pkg update -f

Solution – Alternative Approaches

Pin a known-good regional mirror or use a local package proxy.

Verification & Acceptance Criteria

pkg update completes successfully and package install transactions run without signature warnings.

Rollback Plan

Restore previous repository config and cached metadata snapshot if required.

Prevention & Hardening

Monitor mirror health and automate periodic metadata refresh checks.
