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'


Error org.freedesktop.DBus.Python.dbus.exceptions.DBusException: Tunnel connection failed: 500 Unable to connect
