This is a graphical form of package management; it is based on the APT. This powerful GUI utility enables us to install, update, or remove packages within an easy-to-use environment. Using the synaptic utility enables us to manage packages without requiring us to work at the Command Prompt. Let's take a look at the synaptic utility within the Ubuntu 18 system. The synaptic utility is not installed within Ubuntu 18 by default. We can see information about the synaptic utility before we install it by using the apt-cache command:
root@ubuntu:/home/philip# apt-cache showpkg synaptic
