Issue

• When upgrading from Satellite 6.16 to 6.17 or from 6.17 to 6.18 rubygem-foreman_maintain and satellite-maintain did not update after running satellite-maintain self-upgrade. The required packages remain at older versions, preventing the upgrade to Red Hat Satellite 6.17 or Red Hat Satellite 6.18.
