How to configure automatic updates on Ubuntu 18.04 LTS

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

I just did this for Fedora 29 and am going to do it on my CentOS 7 server when I get a minute.

Our entire fleet has it and it took less time than it would take to do this once on Ubuntu

yeah this is actually easier than fedora imo

Um, no. Fedora is like "install, set to "on" and done." SO easy.

Maybe you save a few seconds? :man_shrugging_light_skin_tone:

How is that so?

unattended-upgrades should already be installed. I didnt have to install it on my stuff.

Other than you are literally copying to config files?

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

[email protected]
[email protected]
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
sudo sed -i "s|^email_host = localhost|email_host = ${EMAILHOST}|" /etc/dnf/automatic.conf
egrep '^email_to|^apply_updates|^emit_via|^email_from|^email_host' /etc/dnf/automatic.conf
# Enable and Start dnf-automatic.timer
sudo systemctl enable --now dnf-automatic.timer

Edit: Missing the setting for the email_host

# Enable and Start dnf-automatic.timer
sudo systemctl enable --now dnf-automatic.timer

It's the same if any difference at all. Although unattended-upgrades should already be installed, so there's that

Maybe its Debian that doesn't have it included.

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

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.
