Taken from vendor docs at https://wiki.debian.org/UnattendedUpgrades

Goal is to have updates ran once per week on Weds mornings.  



sudo apt install unattended-upgrades apt-listchanges
sudo vim /etc/apt/apt.conf.d/20auto-upgrades    default no changes

sudo vim /etc/apt/apt.conf.d/50unattended-upgrades    AND uncomment out the following lines by deleting preceeding //'s  (or just config this file how you want)

# If https://wiki.debian.org/UnattendedUpgrades doesn't work well, uncomment and run it in this script
# unattended-upgrade


# Schedule apt to update regularly via unattended-upgrade.  This script should run slightly afterwards.
# It checks to see if the system needs to be rebooted to load what apt updated.

# Checks to see if a running service is running an old library from memory.
