问题
According to cert-manager installation docs jetstack repository should be added:
$ helm repo add jetstack https://charts.jetstack.io
It gives error message:
Error: looks like "https://charts.jetstack.io" is not a valid chart repository or cannot be reached: error unmarshaling JSON: while decoding JSON: json: unknown field "serverInfo"
What are the ways to fix the issue?

Update 24 Sept 2020
This is now also fixed in Helm 3.3.3. To upgrade to the latest Helm version in Windows choco upgrade kubernetes-helm
