Probably the best guess is: - get a copy of the current yum rpm for CentOS 4 - uninstall the atrpms yum - install the CentOS yum After you have done that look into the protectbase plugin for yum[1]. It can be used to prevent a 3rd party repository (like atrpms) from updating the CentOS base packages, as this is usually not a good idea. An example how it can be enabled for RPMForge[2] is also avaiable in the Wiki[3]. Hope that helps Andreas [1] http://wiki.centos.org/PackageManagement/Yum/ProtectBase [2] http://wiki.centos.org/Repositories/RPMForge [3] http://wiki.centos.org/ -------------- next part -------------- A non-text attachment was scrubbed...
