I came to the conclusion that to manually control unattended upgrades it currently the "easiest" (sarcasm tag on) way to only let the timer update your package list and manually run unattended-upgrades via cron at your desired time.
To do so: # apt-get install unattended-upgrades update-notifier-common # rm /etc/apt/apt.conf.d/20auto-upgrades /etc/apt/apt.conf.d/10periodic # rm /var/log/unattended-upgrades/* # vi /etc/apt/apt.conf.d/20auto-upgrades APT::Periodic::Update-Package-Lists "1"; APT::Periodic::Unattended-Upgrade "0"; # vi /etc/apt/apt.conf.d/local Dpkg::Options { "--force-confdef"; "--force-confold"; } # vi /etc/apt/apt.conf.d/50unattended-upgrades (Thanks to ansible-role at https://github.com/jnv/ansible-role- unattended-upgrades) Ubuntu: ####### // Unattended-Upgrade::Origins-Pattern controls which packages are // upgraded.
