What is apt meaning?

APT stands for "Advanced Package Tool" and is a widely used package management system for Debian-based Linux distributions (such as Ubuntu, Debian, and Linux Mint). The tool allows users to manage installed software packages, install new packages, and update existing packages on their system using a command-line interface. APT simplifies package management by automatically resolving dependencies and conflicts between packages. Additionally, APT keeps track of updates from upstream developers and automatically downloads the latest updates to keep the system up-to-date.
