Symptom & Impact

Install requests fail with modular filtering errors, blocking runtime deployment.

Environment & Reproduction

Seen when required packages depend on a module stream different from the enabled default.

dnf module list
dnf install -y nodejs

Root Cause Analysis

Previously enabled streams lock package sets that conflict with requested versions.

Quick Triage

Review active module streams and candidate providers.

dnf module list --enabled
dnf repoquery --whatprovides nodejs

Step-by-Step Diagnosis

Identify conflicting stream and assess impact of module reset.

dnf module info nodejs
dnf module list nodejs
dnf history userinstalled

Solution – Primary Fix

Reset the module and enable the required stream before install.

dnf module reset -y nodejs
dnf module enable -y nodejs:22
dnf install -y nodejs

Solution – Alternative Approaches

Use a containerized runtime to avoid host stream conflicts.

dnf module disable -y nodejs
podman run --rm container-registry.oracle.com/os/nodejs:22 node -v

Verification & Acceptance Criteria

Requested version installs and module state matches policy.

dnf module list nodejs
node -v
journalctl -xe | tail -n 30

Rollback Plan

Re-enable previous stream and undo transaction if compatibility breaks.

dnf history list
dnf history undo last
dnf module enable -y nodejs:20

Prevention & Hardening

Document approved module streams and enforce in provisioning.

dnf module list --enabled > /root/module-baseline.txt

Related Errors & Cross-Refs

Often appears with repository priority and entitlement channel mismatches.
