Hello @Cloudy
Your diagnosis of the root cause of the HTTP 403 error is correct. At the tail end of last month, Cloudera changed the download policy and now to download Ambari and/or HDP you need a valid subscription.
Please see the announcement here: Transition to private repositories for CDH, HDP and HDF.
The same announcement describes new patch releases of Ambari, which are now required to access Cloudera’s private repositories, which now contain these new and existing releases.
