Symptom & Impact

pkg refuses upgrades due to fingerprint or signature verification failures.

Environment & Reproduction

Often triggered after custom repo changes or stale trusted certificates.

pkg update -f
pkg -vv | grep -i signature -A3

Root Cause Analysis

Repository signing material no longer matches local trust configuration.

Quick Triage

Validate repo URL and signature settings in pkg repo definitions.

grep -R -E 'fingerprints|signature_type' /usr/local/etc/pkg/repos /etc/pkg

Step-by-Step Diagnosis

Review recent log entries and repository trust files for mismatch clues.

tail -n 150 /var/log/messages
ls -lah /usr/share/keys/pkg

Solution – Alternative Approaches

Use a managed internal package mirror with controlled key rotation policy.

Verification & Acceptance Criteria

Package operations proceed without signature validation warnings.

pkg install -y curl

Rollback Plan

Restore prior repo trust files if updated policy breaks expected package sources.

Prevention & Hardening

Track repository trust artifacts in configuration management and audit checksums.

wrong public key, invalid signature, cannot verify repository metadata.
