This look like https://github.com/theforeman/puppetdb_foreman/issues/15 or New foreman/katello install failed - rake aborted! - probably an issue with the puppetdb plugin, there are instructions in that thread regarding disabling it, once you complete the upgrade to a newer supported version you should be able to restore the plugin (seems like version 5.0 has a fix for this issue, but it is only available starting from Foreman 1.20).
