Exactly this. Services and software are not the same thing, you’re asking for a service recommendation and it can’t be open-source software because it’s not software.

I have never met anyone refer to “screen off” as “sleep”.

https://en.wikipedia.org/wiki/Sleep_mode

The terms everybody else are using are: “sleep” = “suspend to RAM” = “S3” and “hibernation” = “suspend to disk”.

Ok so what do you call “sleep”? You’ve now listed suspending, sleeping, and hibernating as 3 different things.

Suspending to disk usually requires a password on resume.

unattended-upgrades can already do that actually, i e. you can configure the systemd timers. But that’s insufficient for my needs. Using a mirror seems like the best option so far.

Sure, bugfix and security.

I’m sorry but I got a lot of very dumb answers like “have a staging environment” and “use a schedule”, even though I listed both this points in my (very short) post already. The most detailed answer I got is a playbook copy/pasted from an LLM, and this one dude was getting into all subthreads to tell me I don’t understand what I’m asking until I blocked him. So you don’t have to worry about me, this was probably my first and last thread on Lemmy ;-) Either way, apologies if I got heated up.

I am not sure what you are taking about. My question is about APT.

This doesn’t seem to enhance my workflow at all. Seems I now would have to reboot, and I still need to find a separate tool to coordinate/stagger updates, like I do now. Or did I miss something?

I can roll back with APT too, my question is how to do the staggered rollout.

I am not worried about upgrades so bad that they literally don’t boot. I am worried about all the possible problems that might break my service.

Go away. You’re here pretending that Ubuntu only does security updates. You have never received a bugfix from Ubuntu? And I am the one who doesn’t know what he’s talking about?

Why do you insert yourself into conversations with other people? I am the one who’s rude?

Which distro is image based and have the staggered rollout feature I’m after?

Ubuntu only does security updates, no?

No, why do you think that?

run your own package mirror

I think you might be on to something here. I could probably do this with a package mirror, updating it daily and rotating the staging, production, etc URLs to serve content as old as I want. This would require a bit of scripting but seems very configurable.

Thanks for the idea! Can’t believe I didn’t think of that. It seems so obvious now, I wonder if someone already made it.

(oops - replied in the wrong place)

Is there anything about staggered upgrades and staging environments in there? Because obviously I had read it before posting…

No, I’m asking how to have unattended-upgrades do that.

Why?
