Synaptic is a graphical user interface (GUI) for managing software packages on Debian-based distributions. If you are using Debian or Ubuntu you will easily find Synaptic in the System Tools menu or in the Administration menu. Synaptic uses the GTK graphic libraries (GNOME’s ones) . So, if you are using GNOME on your debian-based distro you will probably have Synaptic installed as well.
To manage package installations you need administration privileges; so you need to either be root or to authenticate as such. Normally, you will see a window like the one in figure 2 where you can type in the root’s password.
Once Synaptic has started, you will see an interface like the one shown in figure 3. You have a menu on top, then a panel with a few buttons, whose functionality will become clear as you read further into the article.
