That's the thing:  python-gobject2 already exists and the path 
/usr/lib64/python2.7/site-packages/glib exists so not sure.

BTW, after I upgraded rhnlib, I can?t see my Spacewalk repos anymore, that 
is, when I do a yum repolist, I see 0 mirrors.

Subject: [Spacewalk-list] Can't start OSAD in Spacewalk client?

I have Spacewalk v2.6 running on my server.

I was able to register a client to the server, and have osa-dispatcher 
running as well. Now am trying to run osad on the client. I installed the 
osad package and tried to start it and got?

Jun  1 20:12:04 ip-172-31-18-165 systemd: Starting OSAD daemon...
Jun  1 20:12:04 ip-172-31-18-165 osad: Unable to load module osad
Jun  1 20:12:04 ip-172-31-18-165 osad: No module named i18n

So I updated the rhnlib package (per google search), and now I get this?

Jun  1 20:27:51 ip-172-31-18-165 systemd: Starting OSAD daemon...
Jun  1 20:27:51 ip-172-31-18-165 osad: Unable to load module osad
Jun  1 20:27:51 ip-172-31-18-165 osad: cannot import name 
idn_ascii_to_pune


I can?t find anything in the forum about it.

Chris

Perhaps you need to install the package "python-gobject2". 

I can vaguely remember having the same error. It is a bit tricky, because 
the "real error" happens in the try block at line 60 in 
"/usr/share/rhn/up2date_client/hardware.py":

try: # F13 and EL6
    from up2date_client.hardware_gudev import get_devices, 
get_computer_info
    using_gudev = 1
except ImportError:
    from up2date_client.hardware_hal import check_hal_dbus_status, 
get_hal_computer, read_hal
    using_gudev = 0

The try block fails, because 
"/usr/share/rhn/up2date_client/hardware_gudev.py" has:

if dist()[0] == 'SuSE':
    # import gi.repository.GUdev fail and
    # make the import gudev after it fail too
    # so we have to import gudev only
    import gudev
    import glib
    gi_gudev = False

And this fails because "import glib" fails. 
The package "python-gobject2" will install 
"/usr/lib64/python2.7/site-packages/glib"

And if the python module glib is missing, the except block is tried and 
this block fails also, which gives you your error message.

I have to admit that I was too lazy to file a bug report that 
"python-gobject2" should be a dependency for "rhn-client-tools" on SLES.


Regards,
Bernhard

Fouts, Christopher:
> What is the correct procedure from unregistering a currently registered 
Spacewalk client from the Spacewalk server? I know deleting the instance 
from the Spacewalk server GUI is once step, but what about on the client 
side?

You can either remove all client packages
 yum remove rhn* osad spacewalk* yum-rhn-plugin
or just disable spacewalk services
 systemctl disable rhnsd
 systemctl disable rhnmd
 sed -i 's/enabled *= *1/enabled=0/' /etc/yum/pluginconf.d/rhnplugin.conf
