Problem:
When trying to register a Linux client with an RHN Satellite server using the rhnreg_ks utility, the following error is displayed:
Introspect error: The name com.redhat.SubscriptionManager was not provided by any .service files
Background & Analysis:
-
The Linux client was on RHEL 5.8
-
The rhnreg_ks is a utility used to register a Linux client with RHN and is part of the rhn-setup package (rpm).
-
Even though the error was displayed, the Linux client was successfully registered with RHN.
Solution:
I obtained the following solution from this Red Hat Bug Listing. So, here’s what I implemented:
STEP 1: Determine location of rhnreg.py and back it up
sudo grep 'com.redhat.SubscriptionManager' `rpm -ql rhn-client-tools rhn-setup`
For my Linux client, rhnreg.py was located in /usr/share/rhn/up2date_client/
Take a backup of rhnreg.py
STEP 2: Modify rhnreg.py
Comment out the following:
#validity_obj = bus.get_object('com.redhat.SubscriptionManager',
#'/EntitlementStatus')
Add the following just below the commented lines:
validity_obj = bus.ProxyObjectClass(bus,'com.redhat.SubscriptionManager', '/EntitlementStatus', introspect=False)
NOTE: Since you are modifying Python code, ensure that you maintain the program indentation.
Root Cause:
The RHN registration client writes an exception to stderr. The functionality isn’t affected and so this change only has aesthetic value. Perhaps, that’s why I did not find an update in the RHN RHEL 5.8 repository. Anyway, for those of you who find that exception annoying, you now know how to get rid of it.
