Why does the upgrade of Satellite 6.1.9 to 6.2 fail with dependency errors on package 'ruby193-rubygem-ovirt_provision_plugin'?

Issue

• After running step 16 ("yum update") of the upgrade process described in section "6.1.1. Upgrading Satellite Server" I encounter a dependencies error on package ruby193-rubygem-ovirt_provision_plugin-1.0.1.2-1.el7sat.noarch:
