Prior to Konvoy version 1.6.3, there was a known issue where Kommander could not be uninstalled cleanly.
This is documented here for more information:

If you are trying to uninstall Kommander from Konvoy 1.6.3 or later, however, you may notice that the "kubectl delete clusteraddon kommander" command is frozen, or times out.
This is expected behavior. After running the command, you can safely use "ctrl C" to detach from the operation and continue to watch the output of "kubectl get pods -n kommander" as the uninstall runs.
Resources are throttled on this operation in order to minimize impact on the rest of the cluster, so the full uninstall can take up to 30 minutes.
If you are on Konvoy 1.6.3 or later, and suspect that a Kommander uninstall is not completing, please feel free to submit a ticket with our support team:
