Symptom & Impact

Package installs fail because incompatible module streams are enabled, delaying deployments.

Environment & Reproduction

Usually seen after in-place upgrades or role changes on long-lived servers.

sudo dnf module list --enabled

Root Cause Analysis

Multiple streams provide conflicting dependencies and DNF cannot resolve a consistent transaction set.

Quick Triage

Capture current module state and queued transaction details.

sudo dnf -v install 

Step-by-Step Diagnosis

Identify conflicting stream providers and check what each dependency chain requires.

sudo dnf module info 

Solution – Primary Fix

Reset conflicting streams and enable only the target stream before reinstalling packages.

sudo dnf module reset  -y && sudo dnf module enable : -y

Solution – Alternative Approaches

Use AppStream pinning policies or replace module package with a compatible non-modular package.

Verification & Acceptance Criteria

DNF resolves dependencies cleanly and package installs finish without modular conflicts.

Rollback Plan

Re-enable previously used stream and remove newly installed conflicting package set.

Prevention & Hardening

Document approved streams per environment and enforce through configuration management.

Related Errors & Cross-Refs

Conflicts often accompany protected package errors or obsolete dependency loops.
