Q. Why does my yum command fail with an error that a repo is listed more than once under Fedora / RHEL / CentOS Linux? This error occurs when I type yum clean command
ADVERTISEMENTS
Loading “rhnplugin” plugin
Loading “security” pluginRepository xen-repo is listed more than once in the configuration
How do I fix this problem?
A. The above error is caused by a known bug in version 0.5.3-6.el5_2.6 of the package yum-rhn-plugin. The bug is triggered when third party (non-RHN) repositories are configured with Yum.
The recommended workaround is to downgrade the yum-rhn-plugin package to a previous version. To do this, download the old version of the package from the Internet, and then run:
# rpm -Uvh --oldpackage yum-rhn-plugin-0.5.2-3.el5.noarch.rpm

It is colliding with some other repo file.
