I upgrade F13 to F14 and have problems to update one. yum-3.2.28-3.fc13.noarch Fedora release 14 (Branched) And repolist is. 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, Jul 26 2010, 18:19:50) [GCC 4.5.0 20100716 (Red Hat 4.5.0-3)] If you cannot solve this problem yourself, please go to the yum faq at: http://yum.baseurl.org/wiki/Faq And error msg. The backend exited unexpectedly. This is a serious error as the spawned backend did not complete the pending transaction. Any ideas? Cheers. _______________________________________________ Yum mailing list Yum@xxxxxxxxxxxxxxxxx http://lists.baseurl.org/mailman/listinfo/yum
