1. Create a systemd service and a timer unit with the below contents
2. The units must run with root so create the units under /etc/systemd/system/
3. Enable the timer only (systemctl enable --now zypper-dup-download-only.timer)
4. Use zypper dup whenever you ready to update, packages will be cached daily by the units.
