Deleting CRD results in could not list instances: unable to find a custom resource client for addresspools.metallb.io: unable to load root certificates: unable to parse bytes as PEM block

I'm getting the following error when trying to delete the addresspools or bgppeers CRDs.

Installed MetalLB using the metallb Helm chart v0.13.3 from https://metallb.github.io/metallb.
I then deleted the helm install shortly after when I realized it was installed to the wrong namespace.
Running k3s: v1.23.8+k3s2
Using Cilium v1.11.6

Presumably, this is because I deleted the controller before the CA could be populated here. Assuming that's the case, it's probably worth putting a "real" dummy CA so the CRD can be deleted if the controller never started.

Seeking some advice on whether it's safe to force delete the CRD and to see if adding a CA is a valid solution.

So just to understand better the steps, you just installed and deleted the chart right?

In rapid succession, before any of the pods had started.

Understood, thanks for the report

Literally

helm repo add metallb https://metallb.github.io/metallb
helm install metallb metallb/metallb
# sleep 500
helm uninstall metallb
