Ubuntu Auto Upgrade

Configure Ubuntu Auto Upgrade in terminal

• Install dependencies

        sudo apt install unattended-upgrades
      

• Edit /etc/apt/apt.conf.d/50unattended-upgrades and change the following:

        # Enable this setting in Unattended-Upgrade::Allowed-Origins
        "${distro_id}:${distro_codename}-updates";
      

• To keep /boot folder small

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

• Optional:

        # Replace email address with administrator address and insure that email can be sent from cli
        Unattended-Upgrade::Mail "you@some.site";

        # Enable auto reboot
        Unattended-Upgrade::Automatic-Reboot "true";
        Unattended-Upgrade::Automatic-Reboot-Time "02:38";
        # For non-critical servers, add this:
        Unattended-Upgrade::Automatic-Reboot-WithUsers "true";
      

• Edit /etc/apt/apt.conf.d/20auto-upgrades and change the following:

        # Some of these settings may already be active
        APT::Periodic::Update-Package-Lists "1";
        APT::Periodic::Download-Upgradeable-Packages "1";
        APT::Periodic::AutocleanInterval "7";
        APT::Periodic::Unattended-Upgrade "1";
      

• Check if it works:

        sudo unattended-upgrades --dry-run --debug
