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

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

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

                          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

EMAILFROM=postfix@domain.com
EMAILTO=admin@domain.com
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 = root@example.com|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 😛

                                        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

EMAILFROM=postfix@domain.com
EMAILTO=admin@domain.com
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 = root@example.com|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.

                                            Looking over my post, I left out the email_host setting.
