Debian archive proxy and partial mirror builder

apt-proxy automatically builds a Debian HTTP mirror based on requests which pass through the proxy. It's great for multiple Debian machines on the same network with a slower internet link. The archive is automatically kept up to date using http, ftp or rsync. Cache cleaning of unused and old versions is configurable. You can also import the contents of your apt cache into the archive using apt-proxy-import. The suggested packages are needed for the following features: rsync for rsyncd backends, and dpkg-dev for apt-proxy-import.

More information about apt-get remove

Advanced Package Tool, or APT, is a free software user interface that works with core libraries to handle the installation and removal of software on Debian, Ubuntu and other Linux distributions. APT simplifies the process of managing software on Unix-like computer systems by automating the retrieval, configuration and installation of software packages, either from precompiled files or by compiling source code.

apt-get is the command-line tool for handling packages, and may be considered the user's "back-end" to other tools using the APT library.

apt-get remove is identical to install except that packages are removed instead of installed. Note that removing a package leaves its configuration files on the system. If a plus sign is appended to the package name (with no intervening space), the identified package will be installed instead of removed.
