After removing default catalogsource, installed operator went into "CatalogSource not found"

After removing default catalogsource, installed operator went into CatalogSource not found"

1. Install OCP cluster with version  4.12.10  or higher and install the couple of operator provided by Red Hat. 

2. Take backup of default Catlogsource in namespace openshift-marketplace.

# for i in `oc get catsrc --no-headers -n openshift-marketplace | awk '{print $1}'` ; do oc get catsrc -n openshift-marketplace $i -o yaml > $i.yaml; done

3.  Disable the default catalogsource

# oc patch OperatorHub cluster --type json -p '[{"op": "add", "path": "/spec/disableAllDefaultSources", "value": true}]' 
# oc patch operatorhub/cluster --type=merge -p '{"spec":{"sources":[{"disabled":true,"name":"redhat-operators"}]}}' 

4. Now edit the file which we took backup in 2nd step and change name of respective catalogsource for example:

# vi redhat-operators.yaml

name: redhat-operators     << change this name as like redhat-operators-1 . Ultimate goal is to modify each catalogsource name from default to new name.

5. Once default name changed let's create custom catalog using oc create -f
# oc create -f certified-operators.yaml
# oc create -f community-operators.yaml
# oc create -f redhat-marketplace.yaml
# oc create -f redhat-operators.yaml

6. verify with below commands new catalogsource and respective pod must be created.

# oc get catsrc -n openshift-marketplace;oc get pods -n openshift-marketplace

7. Now you will see all previously installed operator will be in "CatalogSource not found" state and you will be get multiple below type of events:

Raw
30s         Warning   ResolutionFailed      namespace/default                                            constraints not satisfiable: subscription businessautomation-operator exists, no operators found from catalog redhat-operators in namespace openshift-marketplace referenced by subscription businessautomation-operator
27s         Warning   ResolutionFailed      namespace/default                                            constraints not satisfiable: no operators found from catalog redhat-operators in namespace openshift-marketplace referenced by subscription businessautomation-operator, subscription businessautomation-operator exists
28s         Warning   ResolutionFailed      namespace/open-cluster-management                            constraints not satisfiable: no operators found from catalog redhat-operators in namespace openshift-marketplace referenced by subscription advanced-cluster-management, subscription advanced-cluster-management exists

all previously installed operator will be in "CatalogSource not found"

without re-installing existing operator this issue must be fixed.
