Upgrade using --from-manifest option causes APIService error

[ihcsim]

When upgrade is performed with the --from-manifest option, the command failed with the following error:

× Failed to parse Kubernetes objects from manifest install-2.5.0.yaml: no kind "APIService" is registered for version "apiregistration.k8s.io/v1" in scheme "pkg/runtime/scheme.go:101"
For troubleshooting help, visit: https://linkerd.io/upgrade/#troubleshooting

It looks like the apiextensions client lib needs to be updated from v1beta1 to v1. When I attempted to fix this, go mod upgraded other k8s serializer-related packages, which are depended upon by controller/gen/client/clientset/versioned/typed/serviceprofile package.

It looks like the decoder doesn't have the scheme to decode apiregistration.k8s.io/v1/APIService.

The workaround is to use the linkerd upgrade command. The only difference is that --from-manifest reads the Linkerd config from a static file, instead of the k8s API.

I believe the reason why some users encountered this error is because the doc instructed them to dump the entire control plane YAML into the manifest file:

# save Linkerd installation manifest
linkerd install > linkerd-install.yaml

From the same doc, this probably makes more sense, and probably won't trigger the error:

kubectl -n linkerd get \
  secret/linkerd-identity-issuer \
  configmap/linkerd-config \
  -oyaml > linkerd-manifests.yaml
