The APT installation method encompasses most other installation methods under the umbrella of the new Package Acquisition code. This method allows installation from locations in the filesystem, ftp and http URLs, supports full installation ordering and dependency checking as well as multiple sources. See the man pages apt-get(8) and sources.list(5) HTTP proxies can be used by setting http_proxy="http://proxy:port/" before running DSelect. FTP proxies require special configuration detailed in the apt.conf(5) man page (see /usr/share/doc/apt/examples/apt.conf)
