Thanks, that sounds like the ideal setup. This solves my problem and I need an APT mirror anyway.
I am probably going to end up with a cronjob similar to yours. Hopefully I can figure out a smart way to share the pool to avoid download 3 copies from upstream.
What do you mean?
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?
Using scheduling is not a good option IMO, it's both too slow (some machines will wait a week to upgrade) and too fast (significant part of machines will upgrade right away).
It seems that making APT mirrors at the cadence I want is the best solution, but thanks for the answer.
I can roll back with APT too, my question is how to do the staggered rollout.
Making multiple mirrors seems like the best solution. I will explore that route.
I was hoping there was something built into APT or unattended-upgrades, I vaguely remembered such a feature... what I was remembering was probably Phased Updates, but those are controlled by Ubuntu not by me, and roll out too fast.
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?
I find it hard to stay courteous in the presence of people like you, who reply without reading my post, call me "duder" and say I "don't understand what I am asking for".
Thankfully, I did get a great answer from someone else.
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.
