+# CentOS Stream 9 Build Fix
+
+## Issue Description
+
+The GitHub Action was failing during the dependency installation step with the error:
+
+```
+No match for argument: python3-venv
+Error: Unable to find a match: python3-venv
+Error: Process completed with exit code 1.
+```
+
+## Root Cause
+
+In CentOS Stream 9, the `python3-venv` package doesn't exist as a separate package. The `venv` module is included directly in the base `python3` package, unlike some other distributions where it's packaged separately.
+
+## Fix Applied
+
+### 1. Updated GitHub Action Workflow
+
+**File**: `.github/workflows/build-rpm.yml`
+
+**Changed**:
+```yaml
+# OLD - BROKEN
+python3-venv \
+
+# NEW - WORKING  
+python3-devel \
+```
+
+### 2. Updated Documentation
+
+**File**: `RPM_PACKAGING.md`
+
+- Updated prerequisite package lists
+- Added specific troubleshooting section for this error
+- Corrected build dependency documentation
+
+## Why This Fix Works
+
+1. **`python3-devel`**: Provides Python development headers needed for compiling native extensions (required by PyInstaller and some PyQt5 components)
+
+2. **Built-in venv**: The `venv` module is available directly via `python3 -m venv` without needing additional packages
+
+3. **CentOS Stream 9 compatibility**: Uses packages that actually exist in the CentOS Stream 9 repositories
+
+## Package Differences by Distribution
+
+| Distribution | Virtual Environment Package | Development Headers |
+|-------------|----------------------------|-------------------|
+| CentOS Stream 9 | Built into `python3` | `python3-devel` |
+| CentOS/RHEL 8 | Built into `python3` | `python3-devel` |
+| Ubuntu/Debian | `python3-venv` | `python3-dev` |
+| Fedora | Built into `python3` | `python3-devel` |
+
+## Verification
+
+After applying this fix, the GitHub Action should:
+
+1. ✅ Successfully install all system dependencies
+2. ✅ Create virtual environment using `python3 -m venv`
+3. ✅ Build the application using PyInstaller
+4. ✅ Create RPM package successfully
+5. ✅ Pass installation tests
+
+## Testing the Fix
+
+To test locally on CentOS Stream 9:
+
+```bash
+# Verify the correct packages are available
+dnf search python3-devel
+dnf info python3
+
+# Test venv creation
+python3 -m venv test_env
+source test_env/bin/activate
+pip install --upgrade pip
+deactivate
+rm -rf test_env
+```
+
+This fix ensures compatibility with CentOS Stream 9's package structure while maintaining the cross-platform enhanced build functionality.
