@thomas.bucaioni You can find out what container runtime is used on you kates nodes with this command
kubectl get nodes -o wideand use the same for crictl.
For example if you want to use containerd runtime you have to use this command:echo "===================================" &&\ echo "Config BEFORE change:" &&\ sudo cat /etc/crictl.yaml &&\ sudo crictl config --set runtime-endpoint=unix:///run/containerd/containerd.sock --set image-endpoint=unix:///run/containerd/containerd.sock &&\ echo "===================================" &&\ echo "Config AFTER change:" &&\ sudo cat /etc/crictl.yaml
