Thank you for the how-to.
I am too spoiled on how to configure auto updates for Fedora and CentOS.

yeah this is actually easier than fedora imo

I don't know about that. I've done so many setups now that I script it.
# Install dnf-automatic
sudo dnf -y install dnf-automatic

EMAILHOST=smtp.domain.com
sudo sed -i "s|^email_to = root|email_to = ${EMAILTO}|" /etc/dnf/automatic.conf
sudo sed -i 's|^apply_updates = no|apply_updates = yes|' /etc/dnf/automatic.conf
sudo sed -i 's|^emit_via = stdio|emit_via = email|' /etc/dnf/automatic.conf
sudo sed -i "s|^email_from = [email protected]|email_from = ${EMAILFROM}|" /etc/dnf/automatic.conf
# Enable and Start dnf-automatic.timer
sudo systemctl enable --now dnf-automatic.timer
Are you installing postfix as well?
No, but I do have a postfix relay server setup for that purpose.

Where do you configure that on the client?

Looking over my post, I left out the email_host setting.
You will enter the name, domain or IP address of the email host

Scripted a bit for anyone interested

FWIW, this line didn't work for me --

sed -i '/Unattended-Upgrade::Skip-Updates-On-Metered-Connections "true"/a\\        "${distro_id}:${distro_codename}-updates";
' /etc/apt/apt.conf.d/50unattended-upgrades

I believe this is due to the line being inserted outside the Unattended-Upgrade::Allowed-Origins grouping.
