Dear Experts:

I tried to update/install the latest RHEL version from RHEL 5.2 version through RHN website. The installation went well for a while and suddenly crashed with the following errors:

*********************************************
Component: pirut
Summary: TB505a298b rhnplugin.py:219:__init__:AttributeError: can't set attribute

************************************************

As the installation/update is incomplete, the system is not stable, and I could not use some of user-end graphics programs which had been working well in the previous RHEL 5.2 version.

Your valuable suggestion is greatly appreciated to resolve this error.

Best regards,
