How to stagger automated upgrade?

remram@lemmy.ml to Linux@lemmy.ml – 40 points –

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.

Minimizing risk is LITERALLY what I asked for. You clearly don't understand what I asked for.

And I in return am asking to you STFU, do some reading, and come back when you're better informed to properly ask for your FREE HELP and get answers.

These are people wasting their time on you right now. You're being a demanding little prick. WE DONT NEED TO GIVE YOU SHIIIIIIIT, BRRAAAAAHHHHH
