Exactly what you'd imagine.

apt-get update
apt-get upgrade
apt-get clean


For more detail, see /usr/lib/apt/apt.systemd.daily --

#  APT::Periodic::Unattended-Upgrade "0";
#  - Run the "unattended-upgrade" security upgrade script 
#    every n-days (0=disabled)
#    Requires the package "unattended-upgrades" and will write
#    a log in /var/log/unattended-upgrades
# 
#  APT::Periodic::AutocleanInterval "0";
#  - Do "apt-get autoclean" every n-days (0=disable)
#
#  APT::Periodic::CleanInterval "0";
#  - Do "apt-get clean" every n-days (0=disable)
