Symptom & Impact

pkg update aborts with signature verification errors and blocks security patching.

Environment & Reproduction

Common after mirror changes or stale local metadata.

sudo pkg update -f

Root Cause Analysis

Local repository metadata or trust material no longer matches the active signed repository state.

Quick Triage

Validate time sync, DNS resolution, and repository reachability first.

date && drill pkg.freebsd.org

Step-by-Step Diagnosis

Inspect repository configuration and active package fingerprints.

cat /etc/pkg/FreeBSD.conf

Solution – Primary Fix

Clear cache and force metadata/bootstrap 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 mirror or route traffic through an internal package proxy.

Verification & Acceptance Criteria

pkg update and install transactions complete without signature warnings.

Rollback Plan

Restore previous repository files and cached metadata snapshot if required.

Prevention & Hardening

Monitor mirror health and periodically validate repository trust chain.

Related Errors & Cross-Refs

Often overlaps with TLS trust failures and stale resolver cache incidents.
