apt

Package management utility for Debian based distributions.

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
