Lab 4 Step 8 - sudo kubeadm upgrade plan

Hi,

I'm trying to follow the lab guides but got stuck with the following command:

sudo kubeadm upgrade plan

I run the labs on VMWare Workstation PRO 15.5
Ubuntu 24.04 LTS
kubeadm version: &version.Info{Major:"1", Minor:"30", GitVersion:"v1.30.1", GitCommit:"6911225c3f747e1cd9d109c305436d08b668f086", GitTreeState:"clean", BuildDate:"2024-05-14T10:49:05Z", GoVersion:"go1.22.2", Compiler:"gc", Platform:"linux/amd64"}

I get following error message:

sudo kubeadm upgrade plan
[preflight] Running pre-flight checks.
[upgrade/config] Reading configuration from the cluster...
[upgrade/config] FYI: You can look at this config file with 'kubectl -n kube-system get cm kubeadm-config -o yaml'

[preflight] If you know what you are doing, you can make a check non-fatal with `--ignore-preflight-errors=...

To see the stack trace of this error execute with --v=5 or higher
`

Output of the same command with --v=10
