      First install unattended-upgrades and postfix

      sudo apt install unattended-upgrades
sudo apt install postfix

      On postfix install select "Internet Site" and keep the default hostname in the next step.

      727862cf-5511-4402-ab54-9b51407c8b1e-image.png

      Next edit the 50unattended-upgrades file

      sudo nano /etc/apt/apt.conf.d/50unattended-upgrades

      Now uncomment the following lines

      "${distro_id}:${distro_codename}-updates";

Unattended-Upgrade::Mail "[email protected]";

Unattended-Upgrade::Remove-Unused-Dependencies "true";

      There are some other options you can configure such as automatic reboots, but I decided not to do so.

      Now we need to configure /etc/apt/apt.conf.d/20auto-upgrades

      sudo nano /etc/apt/apt.conf.d/20auto-upgrades

      Paste the following text in /etc/apt/apt.conf.d/20auto-upgrades. The intervals below are set in days.

      APT::Periodic::Update-Package-Lists "1";
APT::Periodic::Download-Upgradeable-Packages "1";
APT::Periodic::AutocleanInterval "7";
APT::Periodic::Unattended-Upgrade "1";

      Now save and test

      sudo unattended-upgrades

      You should get an email similar to this.

      Unattended upgrade returned: True

              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.

                        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?

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

                                      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.

                                          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.

                                            No, but I do have a postfix relay server setup for that purpose.
