1.4. Troubleshooting failed uninstallation because resources exist

When you uninstall Red Hat Advanced Cluster Management for Kubernetes, the installation fails with the following error message:

Cannot delete MultiClusterHub resource because ManagedCluster resource(s) exist

Cannot delete MultiClusterHub resource because ManagedCluster resource(s) exist

This error occurs when you try to uninstall the Red Hat Advanced Cluster Management hub cluster while it is still managing clusters. All clusters must be removed from management before uninstalling the hub cluster.

Detach all clusters that are still being managed by the hub cluster and try to uninstall again.

For more information about detaching clusters, see the Removing a cluster from management section by selecting the information for your provider in Creating a cluster with Red Hat Advanced Cluster Management for Kubernetes.
