I had a similar issue with a local K8s cluster, in my case the cluster was a k3d/k3s cluster for testing, the issue was that the `traefik` `ingressclass` was already defined and owned by `kube-system` so Helm wasn’t able to install a new one, that’s where the conflict came from.

To verify if you run:

```auto
kubectl get ingressclass traefik -o yaml

```

you would get in the output something like:

```auto
metadata:
  annotations:
    ingressclass.kubernetes.io/is-default-class: "true"
    meta.helm.sh/release-name: traefik
    meta.helm.sh/release-namespace: kube-system

```

I guess in your case it’s `c3` that owns it.

In order to fix this either destroy/re-create the cluster without the `c3` owned `traefik` or you can delete the existing `ingressclass` then try again

```auto
kubectl delete ingressclass traefik

```
