Runner installation fails on kubernetes

I upgrade my AKS kubernetes version to 1.17.9. When I went back to application tabs, it had a button to upgrade the runner so I pushed it. The upgrade failed so I uninstalled, and tried to reinstall. Upon checkeing the kubernetes logs, the error is:

• helm upgrade runner runner/gitlab-runner --install --atomic --cleanup-on-fail --reset-values --version 0.20.1 --set 'rbac.create=true,rbac.enabled=true' --namespace gitlab-managed-apps -f /data/helm/runner/config/values.yaml Error: failed to download "runner/gitlab-runner" (hint: running helm repo update may help)

I don't know exactly what is causing this, but I think helm is being run on my cluster. But it can't find the version of the runner it is looking for.
