Red Hat Satellite engineering is moving the tracking of its product development work on Satellite to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "Satellite project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs will be migrated starting at the end of May. If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "Satellite project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/SAT-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

-----------------

How reproducible:
Easy

Steps to Reproduce:
1. Disable SCA in the Satellite
2. Configure virt-who and run it so that virt-who* hypervisor hosts will be created in Satellite.
3. Attach VDC subscription to the virt-who* hypervisor hosts.
4. Generate the "Subscription - Entitlement Report".

Actual results:
undefined method '#name' for NilClass::Jail (NilClass) (Safemode::NoMethodError)

Expected results:
Report can be generated successfully.


Additional info:
The error is caused by the following 2 lines in the "Subscription - Entitlement Report" template because virt-who* hypervisor hosts don't have any LCE or Content View.

-------------
<%-     report_row(
          'Host Name': host.name,
          'Organization': host.organization,
          'Lifecycle Environment': host.single_lifecycle_environment.name,  <===========
          'Content View': host.single_content_view.name,  <==============
          'Host Collections': host_collections_names(host),
-------------
Comment 1 Jeremy Lenz 2024-01-08 13:44:41 UTC 
As a workaround you could clone the report template and add save navigation:

- 'Content View': host.single_content_view.name,
+ 'Content View': host.single_content_view&.name,
