Hi, I install yum-2.6.1-0.fc5.noarch.rpm and when I try yum check-update I have this error: There was a problem importing one of the Python modules required to run yum. The error leading to this problem was: /usr/lib/python2.4/site-packages/libxml2mod.so: undefined symbol: xmlSchemaIsValid 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: 2.4.2 (#1, Feb 12 2006, 03:59:46) [GCC 4.1.0 20060210 (Red Hat 4.1.0-0.24)] If you cannot solve this problem yourself, please go to the yum faq at: http://wiki.linux.duke.edu/YumFaq Help me, please -- ------------------------------------------------- Cristina Tanzi Tolenti CED - Provincia di Cremona C.so V.Emanuele II, 17 - 26100 Cremona tel. 0372/406362 e-mail cristina.tanzitolenti@xxxxxxxxxxxxxxxxxxxx -------------------------------------------------
