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 Jan Stavel 2017-11-22 15:55:40 UTC 
Description of problem:

A method Unregister of Unregister DBus object gives just a raw message when candlepin server is down.

How reproducible:

   Each time.

Steps to Reproduce:

   subscription-manager unregister

   dbus-send --system --print-reply --dest='com.redhat.RHSM1' '/com/redhat/RHSM1/Unregister' com.redhat.RHSM1.Unregister.Unregister dict:string:string:"",""

Error org.freedesktop.DBus.Python.dbus.exceptions.DBusException: Tunnel connection failed: 503 Service Unavailable

Actual results:

 A raw python exception


Expected results:

   Better self explanatory error message.
Comment 2 Jiri Hnidek 2017-11-24 08:54:38 UTC 
This error is reported, when rhsm.conf includes valid configuration of proxy server and proxy server cannot connect to candlepin server. When no proxy server is used, then following error message is printed:

[root@centos7 ~]# dbus-send --system --print-reply --dest='com.redhat.RHSM1' '/com/redhat/RHSM1/Unregister' com.redhat.RHSM1.Unregister.Unregister dict:string:string:"",""

Error org.freedesktop.DBus.Python.dbus.exceptions.DBusException: [Errno 113] No route to host
Comment 4 Jan Stavel 2018-01-31 12:11:49 UTC 
There is a additional string argument in method call:

error case:
[root@jstavel-rhel7-server ~]# dbus-send --system --print-reply --dest='com.redhat.RHSM1' '/com/redhat/RHSM1/Unregister' com.redhat.RHSM1.Unregister.Unregister dict:string:string:"",""
Error org.freedesktop.DBus.Python.TypeError: Traceback (most recent call last):
  File "/usr/lib64/python2.7/site-packages/dbus/service.py", line 707, in _message_cb
    retval = candidate_method(self, *args, **keywords)
TypeError: Unregister() takes at least 3 arguments (3 given)

right case:
[root@jstavel-rhel7-server ~]# dbus-send --system --print-reply --dest='com.redhat.RHSM1' '/com/redhat/RHSM1/Unregister' com.redhat.RHSM1.Unregister.Unregister dict:string:string:"","" string:""
method return time=1517400605.596377 sender=:1.15120 -> destination=:1.15270 serial=101 reply_serial=2
Comment 5 Jan Stavel 2018-02-01 10:04:47 UTC 
It works:

[root@jstavel-rhel7-server ~]# dbus-send --system --print-reply --dest='com.redhat.RHSM1' /com/redhat/RHSM1/Unregister com.redhat.RHSM1.Unregister.Unregister dict:string:string:'','' string:'en'
