How to stagger automated upgrade?
I am using unattended-upgrades across multiple servers. I would like package updates to be rolled out gradually, either randomly or to a subset of test/staging machines first. Is there a way to do that for APT on Ubuntu?
An obvious option is to set some machines to update on Monday and the others to update on Wednesday, but that only gives me only weekly updates...
The goal of course is to avoid a Crowdstrike-like situation on my Ubuntu machines.
edit: For example. An updated openssh-server comes out. One fifth of the machines updates that day, another fifth updates the next day, and the rest updates 3 days later.

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.
You have no idea what you're asking for, that's why everyone pointed you in one direction, only to have you bitch and complain we "didn't read the post" and whine about it.
