Synaptic-Package-Manager is a graphical front-end to apt, the package management system in Ubuntu and Linux Mint. It combines the point-and-click simplicity of the graphical user interface with the power of the apt-get command line tool. You can install, remove, configure, or upgrade software packages, browse, sort and search the list of available software packages, manage repositories, or upgrade the whole system. You can queue up a number of actions before you execute them. Synaptic will inform you about dependencies (additional packages required by the software package you have chosen) as well as conflicts with other packages that are already installed on your system. The package manager enables the user to install, to upgrade or to remove software packages. To install a package a user must search for the program they want and mark it for installation. Changes are not applied instantly; the user must first mark all changes and then apply them.
