SCRIPT_EXPLAINER="This option will update your server every week on Saturdays at $AUT_UPDATES_TIME:00.
The update will run the built in script '$SCRIPTS/update.sh' which will update both the server packages and Nextcloud itself.\n
You can read more about it here: https://www.techandme.se/nextcloud-update-is-now-fully-automated/
Please keep in mind that automatic updates might fail, which is why it's \
important to have a proper backup in place if you plan to run this option."
