Symptom & Impact

Missing or outdated CA roots cause TLS handshake failures for package and API operations.

Environment & Reproduction

HTTPS tools fail certificate validation even though DNS and routing work correctly.

Root Cause Analysis

Hosts using ca_root_nss from packages or custom trust store paths.

Quick Triage

Root access and ability to reinstall trust packages from verified repositories.

Step-by-Step Diagnosis

[image_ref: 0] Run pkg info ca_root_nss; ls -l /etc/ssl/cert.pem; fetch https://example.com; openssl s_client -connect pkg.FreeBSD.org:443.

Solution – Primary Fix

[image_ref: 1] Ensure expected CA bundle path exists and application-specific SSL settings do not override it incorrectly.

Solution – Alternative Approaches

Reinstall CA bundle with pkg install -f ca_root_nss, relink cert.pem if required, and restart services that cache trust stores.

Verification & Acceptance Criteria

TLS requests complete without trust errors and package update workflows succeed.

Rollback Plan

Revert to previous trusted bundle snapshot if newly installed roots conflict with policy.

Prevention & Hardening

Patch CA packages regularly and audit custom certificate overrides quarterly.

Related Errors & Cross-Refs

Escalate when enterprise interception proxies require managed trust distribution changes.
