By default, this feature is disabled when you installed Ubuntu. The location entry in nautilus lets you use the location box to go to a folder by typing it instead of using to mouse to open one folder at a time until you reach your destination.
This can come in handy if you need to quickly go to a particular location in nautilus without individually opening each folder.
To get started, press Ctrl + Alt + T on your keyboard to open Terminal. When it opens, run the commands below to turn it on.
gsettings set org.gnome.nautilus.preferences always-use-location-entry true
