[ocobles]

The installation has recently started to fail. Replacing containerd with docker containerd.io package fixes this issue.

        [ERROR CRI]: container runtime is not running: output: time="2023-01-25T15:55:02Z" level=fatal msg="validate service connection: CRI v1 runtime API is not implemented for endpoint \"unix:///var/run/containerd/containerd.sock\": rpc error: code = Unimplemented desc = unknown service runtime.v1.RuntimeService"
, error: exit status 1

Actions:

• Replace containerd incuded in default ubuntu repo with containerd.io from docker repo
• Upgrade ubuntu to 22.04
• Upgrade tigera to v3.25

Kubernetes cannot be upgraded to 1.25+ until metallb is upgraded to 0.13+

sed -i.bak -E -e might be a way to keep the \s patterns (which should be more versatile and forgiving to minor changes in the stock config file between OS versions).
