      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

              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.

                            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.
