aufs-source package information
Source for the aufs driver
This package provides the source code for the aufs kernel modules. The aufs package is also required in order to make use of these modules. Kernel source or headers are required to compile these modules. In most cases, a precompiled kernel module is already available. Debian users can install aufs-modules-KERNELVERSION and Ubuntu users can install linux-ubuntu-modules-KERNELVERSION.
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.
