Package Management (Debian/Ubuntu): `apt`, `dpkg`

Welcome to package management! On Linux, software comes in packages. These are archives containing program files, documentation, and metadata.

A package manager is a tool that automates the installation, upgrade, configuration, and removal of software. It handles dependencies, ensuring all necessary components are installed.

On Debian-based systems (like Ubuntu), the fundamental tool for managing packages is dpkg. It's a low-level tool that directly interacts with .deb files (Debian package files).

• dpkg installs, removes, and manages individual .deb packages.
• It does NOT automatically handle dependencies. If a package needs others, you must install them yourself.
