# apt-get clean

# apt install samba

APT 1.0 was released on the 1. April 2014 [0]! The first APT version
was announced on the 1. April exactly 16 years ago [1].

The big news for this version is that we included a new “apt” binary
that combines the most commonly used commands from apt-get and
apt-cache. The commands are the same as their apt-get/apt-cache
counterparts but with slightly different configuration options.
