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.
Yes, Ubuntu DOES only do security updates. They don’t phase major versions of point releases into distro release channels after they have been released. You have no idea what you are talking about in this thread. You need to go do some reading, please. People are trying to help you, and you’re just responding by being rude and snarky. The worst snark as well, because you think you are informed and right, and you’re just embarrassing yourself and annoying the people trying to help you.
