In Satellite 6.2, hosts should not be deleted using the procedure above. One of the features introduced in the release is referred to as "Host Unification". With that feature, a host can include subscription (candlepin) and content (pulp) facets, which means additional objects are stored in the backend services. For this reason, errors like the one above are expected as a means to protect the user. Is there a reason the host is being destroyed with "Host.find_by_name("host.example.test").destroy" as opposed to being destroyed through the UI/CLI/API? If it is failing there, is there anything in foreman-tasks or logs indicating why it is failing?
for me, the reason to want manual deletion is: Katello::Resources::Candlepin::CandlepinResource: 404 Resource Not Found {"displayMessage":"Runtime Error RESTEASY001185: Could not find resource for relative : /consumers//entitlements of full path: https://localhost:8443/candlepin/consumers//entitlements at org.jboss.resteasy.core.registry.PathParamSegment.matchPattern:209","requestUuid":"eccbdfe4-f385-4724-9b5f-1f2a787e5a80"} (GET /candlepin/consumers//entitlements)
The proper way to do this would be: ForemanTasks.sync_task(::Actions::Katello::Host::Destroy, Host.find_by(:name => "host.example.com")) If this fails for some reason you could use: host = Host.find_by(:name => 'host.example.com') host.subscription_facet.try(:destroy! ) if host host.content_facet.try(:destroy!) if host host.destroy if host however this could leave bad data in the backend. This should be able to be fixed with the clean_backend_objects script as part of https://bugzilla.redhat.com/show_bug.cgi?id=1405500 Closing as WONT_FIX
