install apt-get
sudo apt-get install nethack-console
Some packages rely on other packages in order to operate. A programming language may
depend on a compiler, a game engine on graphics files, or an audio player on codecs for play-

Dependencies are one of the biggest reasons for using a package manager like rather
apt
than installing software manually. If a package depends on other packages, will auto-
apt
