Hello. I have recently upgraded from FC3 to FC4 using the guide at http://www.brandonhutchinson.com/Upgrading_Red_Hat_Linux_with_yum.html. After I finished the instructions at that site, running the command: 'yum update' as root returned this result: --------------------------------------------------------------------- The yum libraries do not seem to be availableon your system for this version of python 2.4.1 (#1, May 16 2005, 15:19:29) [GCC 4.0.0 20050512 (Red Hat 4.0.0-5)] Please make sure the package you used to installyum was built for your install of python. --------------------------------------------------------------------- The above is a cut-and-paste, including the spacing. I then tried to solve the problem by re-installing some rpms: libxml2-2.6.20-1.FC4.i386.rpm libxml2-python-2.6.20-1.FC4.i386.rpm libxslt-python-1.1.14-2.i386.rpm python-2.4.1-2.i386.rpm python-devel-2.4.1-2.i386.rpm python-elementtree-1.2.6-4.i386.rpm python-ldap-2.0.6-4.i386.rpm python-sqlite-1.1.6-1.i386.rpm python-urlgrabber-2.9.6-1.noarch.rpm rpm-4.4.1-22.i386.rpm rpm-build-4.4.1-22.i386.rpm rpm-devel-4.4.1-22.i386.rpm rpm-libs-4.4.1-22.i386.rpm xml-common-0.6.3-17.noarch.rpm I had to use the --force option, since 'rpm -Uvh' reported that they were already installed. I also upgraded yum to 2.4.0 via a .src.rpm package, and using the 'rpmbuild --rebuild' command. After I did this, running 'yum update' gives me this message: --------------------------------------------------------------------- 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: 2.4.1 (#1, May 16 2005, 15:19:29) [GCC 4.0.0 20050512 (Red Hat 4.0.0-5)] If you cannot solve this problem yourself, please send this message to <yum@xxxxxxxxxxxxxxxxxxxx>. --------------------------------------------------------------------- I then forcibly downgraded to these RPM's: libxml2-2.6.19-1.i386.rpm libxml2-python-2.6.19-1.i386.rpm rpm-4.4.1-21.i386.rpm rpm-build-4.4.1-21.i386.rpm rpm-devel-4.4.1-21.i386.rpm rpm-libs-4.4.1-21.i386.rpm rpm-python-4.4.1-21.i386.rpm and then I managed to get yum working again. Perhaps there is an incompatibility in the latest versions of yum, rpm, and python? Let me know if you need any more information. Thanks -- Joel
