I am using unattended-upgrades across multiple servers. I would like updates to be rolled out gradually, either randomly or to a subset of test/staging machines first. Is there a way to do that?
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.
The “bot” suggested I use RandomSleep. It’s not effortless.
I got the idea to use systemd timers from another answer in this thread and thought I’d help you out with an Ansible playbook.
In any case, I learned at least two things while reading the other replies, so it wasn’t a total waste. (and you got your answer)
