You seem to have a version of Nethack prior to this package's version,
which is 3.2.2. Unfortunately, the save files and high scores that
older versions used are incompatible with this version, and will be
cleared if you continue installing this package.
If you want to save these, back up /var/lib/games/nethack now!
