More Tips for Debian

Package Management: Learn the various apt commands for managing packages, including installation, updating, upgrading, and removal.

Backports and Third-Party Repositories: Debian Backports offer newer software versions for the stable release. Additionally, consider using third-party repositories when needed, but exercise caution to maintain system stability.

Security Updates: Regularly apply security updates to keep your system secure. Enable automatic updates or set up a regular update schedule.

Systemd: Familiarize yourself with systemd for service management, logging, and system control. Use commands like systemctl to manage services.
