Once the package manager has loaded the next step is to locate the package we need to install. Click on the ''Search'' button the the Synaptic toolbar, enter ''lokkit'' in the Search dialog and press ''Search''. The search should return two results, ''lokkit'' and ''gnome-lokkit''. ''lokkit'' is a text based version of the tool and ''gnome-lokkit'' is a graphical version. ''gnome-lokkit'' requires that ''lokkit'' also be installed so click on the check both next to ''gnome-lokkit'' and select ''Mark for installation'' from the drop down menu. A dialog appears stating that ''lokkit'' also needs to be installed. Click on the ''Mark'' button to also install ''lokkit''.
Now that we have defined what we want to install we now need to installed it. Do do so simply click on the ''APply'' button located in the Synaptic toolbar and click ''Apply'' in the Summary dialog. The package manager will now download and install the tweo packages. Close the completion dialog and exit Synaptic once the installation is finished.
