Package Management: apt

What a package manager does

A package manager downloads, installs, updates and removes software along with its dependencies, so you never manually chase .tar.gz files.

apt basics

On Debian/Ubuntu, apt is the go-to tool. Always update the package index before installing.

sudo apt update              # refresh package index
sudo apt install htop        # install
sudo apt remove htop         # remove
sudo apt upgrade             # upgrade installed packages

Search before installing

apt search keyword finds package names, and apt show pkgname shows details before you commit to installing.
