During the DVD upgrade from F10 -> F11 I encountered the issue that my yum appears broken now: "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: 2.6 (r26:66714, Mar 17 2009, 11:44:21) [GCC 4.4.0 20090313 (Red Hat 4.4.0-0.26)] If you cannot solve this problem yourself, please go to the yum faq at: http://wiki.linux.duke.edu/YumFaq" Could someone please give me a quick pointer how to get yum running? Thanks Stefan btw. I also had the problem that I could not even start the upgraded system because I had the proprietory nvidia driver initially which was obviosly neither upgraded nor deactivated. I could not even get to any kind of console so that I had to use systemrescuecd to edit xorg.conf and activate the nv driver (nouveau does not work either) -- fedora-devel-list mailing list fedora-devel-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/fedora-devel-list
