Whenever I try `helm upgrade longhorn longhorn/longhorn --dry-run` I end up with the following error.

> Error: UPGRADE FAILED: chart requires kubeVersion: \>=v1.18.0 which is incompatible with Kubernetes v1.21.5-3+e8b6c7dca47a08

This looks odd since 1.21.5-3… is definitely newer than 1.18.0. Does anyone know a workaround or a fix?  
Thanks for your help!

Looking at the error, do u have the latest longhorn chart?  
This [charts/Chart.yaml at master · longhorn/charts · GitHub](https://github.com/longhorn/charts/blob/master/charts/longhorn/Chart.yaml) shows its version `1.18.0-0` which will pass the semver comparison to `1.21.5-3...`
