preview-latex requires an Emacs running on a graphics display rather
than in a text terminal since the point of preview-latex is displaying
graphics in the Emacs buffer itself.

The information you give does not suffice to figure out whether you are
intentionally running a non-graphical Emacs.

If you do, preview-latex is uninteresting for you.  Rather use the
"View" menu/commands.  They are generally useful in contrast to
preview-latex.  preview-latex is only interesting for a limited number
of constructs (math ranks rather high there), but for those cases, it
tends to be very nice.
