Red hat / Fedora / CentOS Yum Repo is Listed More Than Once

last updated in Categories , , , , ,

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


Loading “rhnplugin” plugin
Loading “security” plugin

Repository 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

  2. Just change the name of section inside the *.repo file. It is colliding with some other repo file.

    for example:
    [ xen-repo-1]
    [dependency- xen-repo-1]
