- Add complete APT solver implementation (osbuild/solver/apt.py) - Implement Solver interface with dump(), depsolve(), search() methods - Add package info and dependency resolution capabilities - Support for multiple repositories with GPG key validation - Repository priority and component filtering - Proxy support for enterprise environments - Root directory support for chroot environments - Comprehensive error handling and validation - Create extensive test suite (test/test_apt_solver*.py) - Update solver __init__.py with graceful dependency handling - Add comprehensive documentation (docs/apt-solver-implementation.md) This provides native Debian package management capabilities that are not available in upstream osbuild, making debian-forge a true Debian-native image building solution. Closes: APT solver implementation Status: PRODUCTION READY
