APT (en)

- in English

APT (short for Advanced Packaging Tool) is a package management system which finds it origin in the Debian GNU/Linux operating system, and is based on the dpkg package management.

APT was introduced in the Deambox world since OE 2.2. (For dreamboxes with OE 1.6 or OE 2.0, OPKG is used.)

The package management in the shell is a powerful tool for the Dreambox, and offers far more possibilities compared to the package management with the remote control. Of course, using the remote control is easy and most of the time adequate. But maybe this article can convince you to give it a try via Telnet or SSH.

This article explains how to search / install / remove packages and some more interesting commands which offers APT.
