Symptom & Impact

Administrators observe package updates failing with signature verification errors in pkg. Security patching stops and hosts remain exposed until trust configuration is corrected.

Environment & Reproduction

Issue appears after repository key rotation, mirror changes, or stale metadata cache on FreeBSD 15.

freebsd-version -kru
uname -a
pkg -vv | sed -n '1,120p'
pkg update -f

Root Cause Analysis

Most incidents trace to mismatched repository fingerprint, outdated cert bundle, or corrupted pkg cache state after interrupted updates.

Quick Triage

Confirm repository config, DNS reachability, and cert trust path before changing package state.

grep -R "fingerprints|url" /etc/pkg /usr/local/etc/pkg/repos 2>/dev/null
dig +short pkg.FreeBSD.org
fetch -o /dev/null https://pkg.FreeBSD.org

Step-by-Step Diagnosis

Collect verbose pkg and TLS details to isolate trust-chain or mirror problems.

pkg -d update 2>&1 | tail -n 120
ls -la /usr/share/keys/pkg
certctl rehash
truss -o /tmp/pkg.truss pkg update -f || true

Solution – Primary Fix

Refresh trust store and metadata, then force repository refresh.

Solution – Alternative Approaches

If mirror-specific failures persist, switch temporarily to quarterly or nearest supported mirror.

mkdir -p /usr/local/etc/pkg/repos
cp /etc/pkg/FreeBSD.conf /usr/local/etc/pkg/repos/FreeBSD.conf
sed -i '' 's/latest/quarterly/' /usr/local/etc/pkg/repos/FreeBSD.conf
pkg update -f

Verification & Acceptance Criteria

Update and upgrade complete without signature or certificate warnings.

pkg update
pkg upgrade -n
pkg check -d -a
service -e | wc -l

Rollback Plan

Revert repository override and restore prior package state if app regressions appear.

rm -f /usr/local/etc/pkg/repos/FreeBSD.conf
pkg update -f
pkg history | tail -n 20

Prevention & Hardening

Reduce recurrence by pinning approved repository settings and validating trust store in CI checks.

pkg lock ca_root_nss
periodic daily
certctl list | head -n 30

Related patterns include DNS resolution failures, transparent proxy TLS interception, and stale cached package manifests.
