+# Arabic Fonts Installation Fix for Ubuntu 22.04
+
+## Problem Identified
+The Docker build was failing because:
+1. `fonts-scheherazade-new` is not available in Ubuntu 22.04
+2. `fonts-scheherazade` is also not available in Ubuntu 22.04
+
+## Root Cause
+Ubuntu 22.04 (jammy) does not include the Scheherazade font packages in its official repositories.
+
+## Solution Implemented
+1. **Used Available Arabic Fonts**: Replaced unavailable font packages with officially available ones:
+   - `fonts-noto-naskh-arabic`
+   - `fonts-noto-kufi-arabic`
+   - `fonts-hosny-amiri`
+
+2. **Manual Font Installation**: Added direct download of Scheherazade New font from Google Fonts repository:
+   ```dockerfile
+   RUN mkdir -p /usr/share/fonts/truetype/scheherazade \
+       && wget -q https://github.com/google/fonts/raw/main/ofl/scheherazadenew/ScheherazadeNew-Regular.ttf -O /usr/share/fonts/truetype/scheherazade/ScheherazadeNew-Regular.ttf \
+       && wget -q https://github.com/google/fonts/raw/main/ofl/scheherazadenew/ScheherazadeNew-Bold.ttf -O /usr/share/fonts/truetype/scheherazade/ScheherazadeNew-Bold.ttf \
+       && fc-cache -fv
+   ```
+
+## Changes Made
+
+### Dockerfile
+- Removed unavailable font packages (`fonts-scheherazade-new`, `fonts-scheherazade`)
+- Added available Arabic font packages for Ubuntu 22.04
+- Added manual installation of Scheherazade New font from Google Fonts
+- Kept all other packages and configuration the same
+
+## Expected Results
+These changes should resolve the build error and provide comprehensive Arabic font support:
+
+✅ **Build Success**: Docker image will build without font package errors
+✅ **Arabic Support**: Multiple Arabic fonts available for document rendering
+✅ **Scheherazade New**: Manually installed for users who specifically need this font
+✅ **Compatibility**: Maintained Ubuntu 22.04 base image for Hugging Face Spaces compatibility
+
+## Font Options Now Available
+1. **Noto Naskh Arabic** - General Arabic text rendering
+2. **Noto Kufi Arabic** - Modern Arabic UI text
+3. **Amiri** - Classical Arabic typography
+4. **Scheherazade New** - Manually installed from Google Fonts
+5. **Liberation Fonts** - Latin text with Arabic support
+6. **DejaVu Fonts** - Extended character set support
+
+## Verification Steps
+1. Rebuild the Docker image
+2. Verify the image builds without errors
+3. Check that all fonts are properly installed:
+   ```bash
+   fc-list | grep -i arabic
+   fc-list | grep -i scheherazade
+   fc-list | grep -i amiri
+   ```
+4. Test document conversion with Arabic text
+
+## Additional Benefits
+- Better font diversity for Arabic document rendering
+- Fallback options if one font is not available
+- Manual installation ensures latest font versions
+- No dependency on Ubuntu repository availability
