In case of installation failed, then try it one more time.

Mostlyl it could be caused by OpenShift error like:
* Operation cannot be fulfilled on clusterresourcequotas.quota.openshift.io
"core-services-ocp--general": the object has been modified;
please apply your changes to the latest version and try again
