Help me, please.

I work for an ISP and we have several Linux servers running different distros. I am looking for a script that can run an update cronjob on the servers. Some are Ubuntu, some are Rocky, others running Debian and others on Almalinux. We mostly use Rocky but because of some requirements but vendors of some software it's why we have different distros.

I need a way to automate updates on all these servers. This way we don't need to manually check each distro. Anyone know how to do this? Please, help.

Thanks in advance.
