What is APT?

APT, or Advanced Package Tool, is a software utility used to manage the installation, removal, and updating of software packages on Debian-based systems, including Ubuntu and Raspberry Pi OS.

In a Raspberry Pi environment, which typically runs a Debian-based operating system like Raspberry Pi OS, APT is essential.

It allows users to easily install, update, and remove software packages. For instance, with a simple command, you can install a new software package or update all installed software to their latest versions, saving time and effort compared to manual installation.
