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.

    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.
