apt

Package management utility for Debian based distributions. Recommended replacement for apt-get when used interactively in Ubuntu versions 16.04 and later. For equivalent commands in other package managers, see https://wiki.archlinux.org/title/Pacman/Rosetta. More information: https://manpages.debian.org/latest/apt/apt.8.html.

• Update the list of available packages and versions (it's recommended to run this before other apt commands):

sudo apt update

• Search for a given package:

apt search {{package}}

• Show information for a package:

apt show {{package}}

• Install a package, or update it to the latest available version:

sudo apt install {{package}}

• Remove a package (using purge instead also removes its configuration files):

sudo apt remove {{package}}

• Upgrade all installed packages to their newest available versions:

sudo apt upgrade

• List all packages:

apt list

• List installed packages:

apt list --installed
