How to install Ubuntu via text based method?

With your help, I finally got VNC working and I'm connected from my Windows to a remote server with Linux, Xorg and KFCE. And now I'm looking at a text based interface that's in a window, instead of before when I was only looking at a text based command line. Now, how do I install and run something like Ubuntu? Do I apt-get the webpage in which the tar image of Ubuntu is, and then install the file from the folder it's downloaded into? I did a yum groupinstall gnome window environment thinking that that would give me the OS I was looking for, but when I type in startx, I just get Quote: AttributeError: DBusException instance has no attribute '_dbus_error_name' and when I copy that, I get: Quote: waiting for X server to shut down Window manager warning: The application 'eggcups' lost its connection to the display :0.0; most likely the X server was shut down or you killed/destroyed the application. The application 'gnome-panel' lost its connection to the display :0.0; most likely the X server was shut down or you killed/destroyed the application.
