Hi, does anyone know how to fix the following error: [root@nas01 /]# yum upgrade There was a problem importing one of the Python modules required to run yum. The error leading to this problem was: No module named yum 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: 2.3.4 (#1, Feb 22 2005, 04:09:37) [GCC 3.4.3 20041212 (Red Hat 3.4.3-9.EL4)] If you cannot solve this problem yourself, please go to the yum faq at: http://wiki.linux.duke.edu/YumFaq Thanks!
