Symptom & Impact

Package operations fail globally and prevent patching or software installation.

Environment & Reproduction

Usually follows power loss or forced termination during DNF transactions.

dnf check
rpm -qa | head
rpm --rebuilddb --help

Root Cause Analysis

Partial writes and stale lock artifacts can invalidate RPM metadata consistency.

Quick Triage

Confirm corruption and gather transaction history before repair.

dnf history
rpm -Va --nofiles --nodigest
ls -la /var/lib/rpm

Step-by-Step Diagnosis

Validate db files and check active lock contention.

fuser -v /var/lib/rpm/.rpm.lock || true
cp -a /var/lib/rpm /var/lib/rpm.backup
rpm -qa > /root/rpm-before.txt

Solution – Alternative Approaches

Use rescue mode for offline package database repair if needed.

dnf reinstall -y rpm dnf
dnf check
dnf upgrade --refresh -y

Verification & Acceptance Criteria

Package queries and upgrades complete without database errors.

rpm -qa | wc -l
dnf check
journalctl -p err -n 50

Rollback Plan

Restore rpmdb backup if rebuild produces unresolved package state.

rm -rf /var/lib/rpm
cp -a /var/lib/rpm.backup /var/lib/rpm
rpm --rebuilddb

Prevention & Hardening

Protect update windows with reliable power and controlled reboot policies.

systemctl status dnf-automatic.timer
journalctl -u dnf-automatic --since yesterday

Often linked to filesystem integrity issues and low disk space incidents.
