- registering  
Traceback (most recent call last):  
File “/usr/sbin/rhnreg\_ks”, line 25, in ?  
from rhn.connections import idn\_pune\_to\_unicode  
ImportError: cannot import name idn\_pune\_to\_unicode

\*\*\* Error: Registering the system failed.

‘unknown’: I need something more specific.

Any suggestion here?

The information you provided is too sparse to give any advice. I’d suggest to open a regular support request and provide additional data, like

- full logs
- full information about the system (_exact_ centos version, architecture, rpm list, enabled repositories, etc.)
