APT (Advanced Packaging Tool) is a powerful package management system, on which the graphical programs Add/Remove Programs and Adept are based. APT automatically handles dependencies and performs other operations on system packages to allow the installation of the desired packages.


Running APT requires administrative privileges (see the section called "Root And Sudo").

Some common commands that can be used with APT:

  • Install packages:

    sudo apt-get install packagename

  • Remove packages:

    sudo apt-get remove packagename

  • Search for packages:

    apt-cache search keyword

  • Retrieve new lists of available packages:

    sudo apt-get update

  • Upgrade system with available updates:

    sudo apt-get dist-upgrade

  • List further commands and options:

    apt-get help


For further information about the use of APT, you can read the comprehensive Debian APT User Manual.
