Uninstall the Helm and Catalog services

The catalog-ui and helm services are no longer available starting from version 3.6.x. If you installed these services previously they are still available, but will not receive future updates. You can uninstall these services if you confirm they are no longer needed.

Required user type or access level: Cluster administrator

Important: Do not uninstall the Helm and Catalog services unless you are certain they are no longer needed. Removing the Helm and Catalog services when they are still required can damage or break your environment. Some IBM Cloud Paks and components might rely on these services.

Scripted uninstall of the Helm and Catalog services

Create a script, for example, uninstall_helm_operators.sh and add the following code.

Set the permissions on the script and run it by specifying the namespace and main operandrequest name.

For example:
```
./uninstall_helm_operators.sh ibm-common-services common-service
```
