+# Build Fixes Summary
+
+## Problem Identified
+The Docker build was failing with:
+```
+E: Unable to locate package fonts-scheherazade-new
+```
+
+## Root Cause
+The package `fonts-scheherazade-new` is not available in Ubuntu 22.04 (jammy), it's only available in Ubuntu 24.04 (noble) and later versions.
+
+## Solution Implemented
+1. **Fixed Package Name**: Changed `fonts-scheherazade-new` to `fonts-scheherazade` which is the correct package name for Ubuntu 22.04
+2. **Updated Cairo Font URL**: Changed to a more reliable source for Cairo font installation
+3. **Maintained Compatibility**: Kept Ubuntu 22.04 as the base image to ensure compatibility with Hugging Face Spaces
+
+## Changes Made
+
+### Dockerfile
+- Replaced `fonts-scheherazade-new` with `fonts-scheherazade`
+- Kept all other packages and configuration the same
+- Maintained Java-disabling environment variables
+- Preserved unoconv installation for fallback conversion
+
+### app.py
+- Updated Cairo font URL to a more reliable source
+- Kept all other Java-disabling logic and fallback mechanisms
+
+## Expected Results
+These changes should resolve the build error and allow the Docker image to build successfully while maintaining all the Java-disabling and fallback conversion features.
+
+## Verification Steps
+1. Rebuild the Docker image
+2. Verify the image builds without errors
+3. Test document conversion to ensure all functionality works
+4. Check that Java is properly disabled
+5. Verify font installation works correctly
+
+## Additional Notes
+- The `fonts-scheherazade` package provides the Scheherazade font which is suitable for Arabic text rendering
+- The fallback mechanisms for conversion (LibreOffice → unoconv) remain in place
+- All Java-disabling features are preserved
+- Font installation improvements should provide better Arabic text support
