Upgrade failed

[bpopovich44]

I received this error while trying to install certs to rancher UI using command:
helm upgrade rancher rancher-stable/rancher --namespace cattle-system --set hostname=rancher.xxx.com --set replicas=3 --set ingress.tls.source=secret --set privateCA=true
UPGRADE FAILED: chart requires kubeVersion: < 1.27.0-0 which is incompatible with Kubernetes v1.27.10+rke2r1
I am currently on rke2 version 1.27.10+rke2r1. Can this be fixed with updating helm or do I need to downgrade kube version?
To downgrade, would I run the install script but use a version?
Can you give me the commands for the master and worker nodes to downgrade, I don't see them posted.

Thank you.

1. Check the Rancher compatibility matrix. Kubernetes 1.27 should be supported by Rancher 2.8.
2. Downgrades are not supported.

Thank you Brandon. Looks like I'm on rancher 2.7.9. So I need to upgrade Rancher through helm?

Yep. rancher/rancher would be the correct place for this discussion though.

Ok. Thank you Brandon
