What did you do

I followed the Quick Start https://k3d.io/stable/#quick-start

  • How was the cluster created?

    • k3d cluster create --trace --no-rollback mycluster
    • k3d kubeconfig merge mycluster --kubeconfig-switch-context

  • What did you do afterwards?

    • kubectl cluster-info

What did you expect to happen

A successful output of kubectl cluster info

Screenshots or terminal output

Output of kubectl cluster-info

To further debug and diagnose cluster problems, use 'kubectl cluster-info dump'.

some things I want to say

After some time I thought if it was something with what my Linux Distributions is distributing, like an old version. But then I tested the same thing on my notebook, which has the same Linux Distro + Packages installed, and it worked flawlessy, so I really don't know anymore where to search for errors

Here is also the trace log of k3d create cluster mycluster: trace_log.txt
