Thank you very much for the reply. "showdupesfromrepos=1" is added to yum.conf and now "yum list" shows all the packages. I have one more question: For a normal Fedora/CentOS system, this option is not set by default in yum.conf. However, "yum list" still shows both base packages and update packages. Why? Thanks.
