Using CentOS 5.1. The page http://wiki.centos.org/PackageManagement/Yum/Priorities states that: "The priorities plugin is available from two locations: ... * The priorities plugin has been added to yum-utils since yum-utils 1.0.1. The version included with yum-utils works with both yum 2.4.x and 3.0.x. Installation instructions are provided in the README file that is included in the plugins/priorities directory of the archive." So I've installed yum-utils instead of yum-priorities and there is no plugin on that package. [miguel at friends ~]$ rpm -q yum-utils yum-utils-1.0.4-3.el5.centos.2 [miguel at friends ~]$ rpm -ql yum-utils /usr/bin/package-cleanup /usr/bin/repo-graph /usr/bin/repo-rss /usr/bin/repoclosure /usr/bin/repomanage /usr/bin/repoquery /usr/bin/reposync /usr/bin/repotrack /usr/bin/yum-builddep /usr/bin/yumdownloader /usr/share/doc/yum-utils-1.0.4 /usr/share/doc/yum-utils-1.0.4/COPYING /usr/share/doc/yum-utils-1.0.4/README /usr/share/man/man1/package-cleanup.1.gz /usr/share/man/man1/repo-rss.1.gz /usr/share/man/man1/repoquery.1.gz /usr/share/man/man1/yum-builddep.1.gz /usr/share/man/man1/yum-changelog.1.gz /usr/share/man/man1/yumdownloader.1.gz Installing the yum-priorities package actually installed the plugin. [miguel at friends ~]$ rpm -q yum-priorities yum-priorities-1.0.4-3.el5.centos.2 [miguel at friends ~]$ rpm -ql yum-priorities /etc/yum/pluginconf.d/priorities.conf /usr/lib/yum-plugins/priorities.py /usr/lib/yum-plugins/priorities.pyc /usr/lib/yum-plugins/priorities.pyo Did I miss something?
