Install .deb

Packages are manually installed via the dpkg command (Debian Package Management System). dpkg is the backend to commands like apt-get and aptitude, which in turn are the backend for GUI install apps like the Software Center and Synaptic.

Install a package:

To install a downloaded Debian (Ubuntu) package (.deb): Open Terminal and type

sudo dpkg -i DEB_PACKAGE

To remove a Debian (Ubuntu) package (.deb):

sudo dpkg -r PACKAGE_NAME

To Reconfigure/Repair an installed Debian (Ubuntu) package (.deb):

sudo dpkg-reconfigure packagename
