I recently installed a chess program called xboard. I tried to open it from the terminal and it gave me the following error.
dineshkumar@dineshkumar-desktop:~$ xboard
xboard: no fonts match pattern -*-helvetica-bold-r-normal--*-*-*-*-*-*-*-*
Some fonts seem to be missing in your system, you should install either xfonts-100dpi or
xfonts-75dpi and then restart Xorg to get xboard running.
See http://bugs.debian.org/504077 and http://bugs.debian.org/562726 for more information.
What does this means and how do I rectify it and run xboard?
