cert-manager v0.5.2 install broken on Helm v2.12.0

[abevoelker]

Ran through this today after previous success (well, previous cert-manager bugs notwithstanding), and got the following error: cert-manager/cert-manager#1144

+1 I have the same error installing with KinD.

Looks like you might've installed the chart before? The other day I realized the Helm chart doesn't correctly uninstall the CRDs. But you can delete those CRDs manually and reinstall the chart.

If this is the issue you're seeing, please upvote: cert-manager/cert-manager#1152

Nope, this happens on freshly-created clusters on first install.

As for workarounds, couldn't downgrade to Helm 2.11 due to a Helm bug with helm reset

However as others in cert-manager/cert-manager#1144 said, installing cert-manager 0.4.1 then upgrading worked okay:

$ helm del --purge cert-manager
$ helm install --name cert-manager --version v0.4.1 \
    --namespace kube-system stable/cert-manager
$ helm upgrade cert-manager stable/cert-manager
