RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 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 "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". 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 "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-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.

Description John Sefler 2023-04-25 20:39:30 UTC 
Description of problem:
After setting a bad proxy on a registered system, a call to subscription-manager status encounters "'NoneType' object has no attribute 'get'".  This was handled more gracefully on RHEL-9.2


Version-Release number of selected component (if applicable):
[root@kvm-02-guest13 ~]# rpm -q subscription-manager
subscription-manager-1.29.34-1.el9.x86_64


How reproducible:


Steps to Reproduce:
[root@kvm-02-guest13 ~]# subscription-manager register --username=stage_rhsmqe_testuser01 
Registering to: subscription.rhsm.stage.redhat.com:443/subscription
Password: 
The system has been registered with ID: 2e081dce-45e3-4023-9a40-0f81c5ed7034
The registered system name is: kvm-02-guest13.lab.eng.rdu2.redhat.com
[root@kvm-02-guest13 ~]# 
[root@kvm-02-guest13 ~]# subscription-manager config --server.proxy_hostname=bad-proxy --server.proxy_port=3127
[root@kvm-02-guest13 ~]# 
[root@kvm-02-guest13 ~]# subscription-manager status
+-------------------------------------------+
   System Status Details
+-------------------------------------------+
Overall Status: Invalid

Red Hat Enterprise Linux for x86_64 Beta:
- Not supported by a valid subscription.

System Purpose Status: Unknown
'NoneType' object has no attribute 'get'
[root@kvm-02-guest13 ~]# echo $?
70


Actual results:
  above

Expected results:
  exitCode 1 (without the 'NoneType' object error)

Comment 1 John Sefler 2023-04-25 20:44:21 UTC 
For comparison, the same scenario on RHEL-9.2 follows with more graceful error handling...

Comment 2 Pino Toscano 2023-04-27 04:50:47 UTC 
Reproduced easily (though I really needed to change the config, rather than pass --proxy to 'sub-man status'), thanks.
This is a small regression introduced by the recent internal cache rework (part of [1]); nothing bad in the end, simply a lack of tests (sigh), hopefully easily fixed by:
