Symptom & Impact

dnf and rpm commands fail with database corruption or header read errors.

Environment & Reproduction

Abrupt shutdown or filesystem issues damaged Berkeley DB or sqlite RPM metadata files.

Root Cause Analysis

Run rpm –verifydb and inspect disk health logs using journalctl -k for IO errors.

Quick Triage

Back up /var/lib/rpm and ensure enough disk space before any recovery operation.

Step-by-Step Diagnosis

Run rpm –rebuilddb and clear stale dnf caches to regenerate consistent metadata.

Solution – Primary Fix

Execute a test install query with dnf to confirm package operations are functional.

Solution – Alternative Approaches

Confirm rpm -qa works and dnf history list returns without errors.

Verification & Acceptance Criteria

If rebuild fails, restore rpmdb backup and investigate filesystem integrity first.

Rollback Plan

Avoid forced power-offs during updates and maintain filesystem health checks.

Prevention & Hardening

Alert on rpmdb error patterns in update jobs and package management services.

Related Errors & Cross-Refs

Add pre-upgrade checks for rpmdb and disk health in maintenance workflows.
