Doc Text:	Cause: dbus is not included in a minimal install Consequence: rhsmcertd will swallow tracebacks due to missing dbus and therefore cannot communicate to candlepin/sam/katello (subscription management servers) on a daemon like basis. Fix: yum install dbus Result: rhsmcertd will operate normally.	Story Points:	---

Description Og Maciel 2012-01-27 20:02:22 UTC

Description of problem:

Seems that we have a dependency on DBUS and friends being installed in a client in order for subscription-manager to send packages information during a registration. Is this assumption correct? My RHEL 6.1 system was installed using the "minimal" installation option in Anaconda, and apparently this option does not install DBUS by default. Registering a system with the instructions detailed here (https://fedorahosted.org/katello/wiki/GuideSystemRegistrationClient#RegisteringfromtheClient) failed to submit packages information back to the katello server. The detailed error from rhsm.log follows.

Version-Release number of selected component (if applicable):

Katello Version: 0.1.199-1.el6

How reproducible:


Steps to Reproduce:
1. Boot a "minimal" installation of RHEL 6.1
2. Attempt to register it following the instructions in the aforementioned wiki page
3.
  
Actual results:

The system does get registered but when you browse its' Software or Packages tab in the web ui, nothing is displayed.


Expected results:

Comment 1 Miroslav Suchý 2012-08-21 17:03:03 UTC

This is related to subscription manager.

Comment 3 Bryan Kearney 2012-10-12 14:58:03 UTC

Latest spec file includes dbus items, so this should be resolved. Moving to on_qa for verification.

Comment 6 J.C. Molet 2012-12-12 15:27:01 UTC

Testing with a minimal install of the latest 6.4 release candidate with included: 
subscription-manager-1.1.11-1.el6.x86_64

Although python-dbus is a dependency now, it pulls down a few dbus related libraries but not dbus itself:

# rpm -qa | grep dbus
dbus-libs-1.2.24-7.el6_3.x86_64
dbus-python-0.83.0-6.1.el6.x86_64
dbus-glib-0.86-5.el6.x86_64

I don't believe dbus will get installed until subscription-manager-gui is installed (which requires dbus-x11).

That being said, I cannot reproduce this traceback either by subscribing or running rhsmcertd directly.  It seems now that if subscription-manager detects that dbus is not running, it quietly exits.

So I have verified that the traceback has been cleaned up, but I'm not convinced the expected results have been satisfied.

Comment 7 J.C. Molet 2012-12-13 16:42:57 UTC

I'm marking this VERIFIED due to the results in comment 6 for the following reasons:

1) The traceback has been fixed.
2) The purpose of a minimal install is just to be a starting point to install other packages - which we currently can do.
3) The fix would be to register the system and run 'yum install dbus'
