Operating Systems

Debian is a foundational open-source Linux distribution known for its stability, extensive package repositories, and strict adherence to free software principles. It forms the base for many popular distributions, including Ubuntu. Despite its robustness, administrators and users sometimes encounter challenges such as package conflicts, repository signature errors, boot problems, network configuration failures, and system performance bottlenecks. Troubleshooting Debian effectively requires a deep understanding of APT package management, systemd service control, kernel management, and Debian's structured configuration systems.
