Hello there, I just upgraded from fedora core 3 to Fedora Core 4. Python was upgraded from 2.3 to 2.4. At first boot in Core 4 i launched a yum check-update, but i had the following : yum The yum libraries do not seem to be available on 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 install yum was built for your install of python. I then uninstalled yum and went for a new one to install it once again. I still have the error. Tried to uninstall python 2.4 but there is too many dependencies. Anyway i also still have python 2.3 in /usr/lib. How can i have my yum back and working without re-installing my system ? --- FORTUNE says : Skill without imagination is craftsmanship and gives us many useful objects such as wickerwork picnic baskets.
