Synaptic is a graphical package management program for apt. It provides the same features as the apt-get command line utility with a GUI front-end based on Gtk+. If you prefer using a GUI to install apps in Debian and Debian-based systems (ubuntu, mint, etc) synaptic would make it worthwhile.
How to install:
On the command terminal (SHORTCUT=> Ctrl+Alt+T), enter:
sudo apt-get update sudo apt-get install synaptic
Ubuntu 16.04 (Xenial)was used here. You could grab the binary (.deb) package from here.
After installation you can now use synaptic to install/upgrade/remove any software package you want in your system. Using the search feature you can just type in the name of the software package you want to install and then synaptic would do the search for you and install it along with it dependencies.
