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.
That doesn’t even have anything to do with this. Phased upgrades are about CHANNELS. As in a select number of systems get the upgrades before anyone else. This is similar to a staging environment in that it minimizes risk. You clearly do not understand what you are asking for here, and are unable to articulate it well enough for us to understand either. I suggest you ask in a different way with more information.
Minimizing risk is LITERALLY what I asked for. You clearly don’t understand what I asked for.
