[navatweb]

In my Cluster I don't have PodDisruptionBudget. I downloaded the yaml "https://raw.githubusercontent.com/open-policy-agent/gatekeeper/v3.14.0/deploy/gatekeeper.yaml"
and commented out that the section on PodDisruptionBudget. Did kubectl -f apply and the installation completed without error.
I hope I don't have to use PodDisruptionBudget

Please take a look at installing with helm as it has many more conditional options for you to choose from as every environment is quite different. e.g https://github.com/open-policy-agent/gatekeeper/blob/master/charts/gatekeeper/templates/gatekeeper-controller-manager-poddisruptionbudget.yaml gets installed only if the cluster has the pdb capability.
