We haven't tested it on ubuntu22.04 yet.

Was gonna test this on 22.04 myself. However I saw this issue. You say that 22.04 isn't tested yet. Is there any table or page that indicates operating systems that are tested?

aufs-tools was required for docker.io originally and the dependency has been removed from docker.io since ubuntu22.04 according to https://bugs.launchpad.net/ubuntu/+source/aufs-tools/+bug/1947004
It is fine to remove aufs-tools from roles/kubernetes/preinstall/vars/ubuntu.yml for ubuntu22.04.

Is this also a required work around when using containerd instead of Docker?

I did try this. And the whole playbook run smooth, after removing aufs-tools, on 3 Ubuntu 22.04 server (bare metal). And so far no issue with the Kubernetes cluster (Except the fact it was needed to upgrade calico version)

I'm guessing on 20.04 we should default to using overlayfs2 anyway even for docker so for me it looks like a sensible change.

That is a nice point.
At this time, the default container_manager is containerd not docker on Kubespray.
I tried to test some patterns after deleting aufs-tools from roles/kubernetes/preinstall/vars/ubuntu.yml

• container_manager: containerd on Ubuntu 18.04: Works
• container_manager: docker on Ubuntu 18.04: Works

docker-ce(not docker.io) is installed on Ubuntu 18.04 for container_manager: docker.
So I think we just can remove aufs-tools from the requirement.
