i'm at wits' end. after upgrading in-place an FC4 box to FC5, i'm unable to run yum, or any of the yum utils, or up2date. i've tried reinstalling, with --force, all of yum, libxml2, and libxml2-python, and still i'm getting the following: __________ [root@speedlimit35 yum-utils-0.5]# yum 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: xmlTextReaderSchemaValidateCtxt 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 ___________ what's really bizarre is that, when i booted via the DVD into rescue mode, and did my 'chroot /mnt/sysimage', i *was* able to successfully run yum, and installed a few packages at that time. however, when i rebooted from disk, the above error was back in all its gory glory. i'm pretty sure there's a clue there to what the true problem is, but damned if i can figure out what it might be... at this point, i'm seriously considering doing an rpm -e on the entire python dependency base, and reinstalling it all over again. hopefully, however, one of you gentle souls will share with me the proper incantation to mutter, with the appropriate amount of goat's blood and chicken bones to employ, that will spare me from that dreadful endeavor! TIA.
