Symptom & Impact

Package installs fail due to modular filtering and stream incompatibility.

Environment & Reproduction

Mixed module streams enabled across environments.

dnf module list --enabled
dnf install 

Root Cause Analysis

An enabled stream constrains package versions that conflict with requested dependencies.

Quick Triage

Identify enabled module streams and candidate package providers.

dnf module list
dnf repoquery --whatprovides 

Step-by-Step Diagnosis

Inspect solver output for filtered packages and conflicts.

dnf -v install 
dnf module info 

Solution – Primary Fix

Reset conflicting stream and enable the intended stream.

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

Solution – Alternative Approaches

Use environment-specific module policy files to avoid accidental stream drift.

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

Verification & Acceptance Criteria

Dependency resolution completes and package installs without modular errors.

dnf check
rpm -q 

Rollback Plan

Re-enable previous stream if application compatibility tests fail.

dnf module reset -y 
dnf module enable -y :

Prevention & Hardening

Document approved module streams per workload tier.

dnf module list --enabled
dnf history userinstalled

Related Errors & Cross-Refs

modular filtering, conflicting requests, package is filtered out by modular filtering.
