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: 2.7 (r27:82500, Sep 16 2010, 18:02:00) [GCC 4.5.1 20100907 (Red Hat 4.5.1-3)] If you cannot solve this problem yourself, please go to the yum faq at: http://yum.baseurl.org/wiki/Faq
> rpm -i yum-3.2.28-3.fc14.noarch.rpm Don't use "rpm -i", this does install which is not what you want. The problem you have hit, I think, is that the version of yum you had in Fedora 12 (from updates) is newer than the version of yum in Fedora 14 (or Fedora 13). This shouldn't happen, but it has. The way to downgrade via. rpm is to run: rpm -Uvh --oldpackage yum-3.2.28-3.fc14.noarch.rpm
