Symptom & Impact

Containers built with podman fail to run on cri-o with image format errors.

Environment & Reproduction

Triggered when podman is upgraded ahead of cri-o on the same node.

Root Cause Analysis

cri-o pins a compatible runc/containers-common stack; podman pulls newer images.

Quick Triage

rpm -q podman cri-o containers-common shows version skew.

Step-by-Step Diagnosis

crio –version and podman info | grep -i version compared against release notes.

Solution – Primary Fix

Align versions by enabling the matching CentOS Stream 9 module: dnf module enable cri-o:.

Solution – Alternative Approaches

Pin podman via dnf versionlock until cri-o catches up.

Verification & Acceptance Criteria

kubectl run test –image= succeeds on the node.

Rollback Plan

Downgrade podman with dnf downgrade podman to last known-good RPM.

Prevention & Hardening

Use a single container engine per host and patch them together.
