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.
It’s called a staging environment. You have servers you apply changes to first before going to production.
I assume you mean this for home though, so take a small number of your machines and have them run unattended upgrades daily, and set whatever you’re worried about to only run them every few weeks or something.

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