APT

From dankwiki

The package manager for Debian and its derivatives. Raptorial is a reimplementation of portions of APT.

Config

Dump the config via apt-config dump.

To disable retention of downloaded packages in the archive directory, add APT::Keep-Downloaded-Packages "false"; to the config. Note that the Binary::apt::APT::Keep-Downloaded-Packages variable only applies to the apt binary, not e.g. apt-get.
