What’s the Best Central Update Solution for Ubuntu and Linux Systems?

I've been working mostly with Windows, but now I'm diving into Linux, particularly Ubuntu, and I'm on the lookout for a solid solution to manage updates across my environment. I'm using AWX for deployment but still have some network devices that I've set up manually. Ideally, I'd love a solution that can handle updates for servers, containerized environments, and network gear, whether all at once or one at a time. Any recommendations? I'd prefer something open-source if possible!
