From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

How to stagger automated upgrade? (lemmy.ml)

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.

Yeah no the other poster is correct, I meant Ubuntu doesn't do feature updates after release. You seem worried about something that's quite unlikely to happen (breakage introduced from minimal patches), while delaying security fixes. And I assume the vast majority of updates are security fixes.

And I also think you're being rude in this whole thread.

Sure, bugfix and security.

I'm sorry but I got a lot of very dumb answers like "have a staging environment" and "use a schedule", even though I listed both this points in my (very short) post already. The most detailed answer I got is a playbook copy/pasted from an LLM, and this one dude was getting into all subthreads to tell me I don't understand what I'm asking until I blocked him. So you don't have to worry about me, this was probably my first and last thread on Lemmy ;-) Either way, apologies if I got heated up.
