Hello, I installed yumex, using yum. It updated and installed various items, among which was urlgrabber.noarch 0:2.9.6-1. When I tried to use yum (command line) later I got the following message: There was a problem importing one of the Python modules required to run yum. The error leading to this problem was: No module named urlgrabber Please install a package which provides this module, or verify that the module is installed correctly. It's possible that the above module doesn't match the current version of Python, which is: 2.4.1 (#1, Jun 20 2005, 22:41:40) [GCC 3.4.3 20050227 (Red Hat 3.4.3-22.1)] If you cannot solve this problem yourself, please send this message to <yum@xxxxxxxxxxxxxxxxxxxx>. ************ My distro is Scientific Linux 4.1 i386; kernel 2.6.9-11.EL I am a linux newbie so please help with as much detail as you can! Thank you much. Penny
