2.2.36 Upgrading rhn-client-tools
The expiration date for the Oracle Linux 6 GPG key has been extended in this update. If you install the rhn-client-tools package and the installed version of the oraclelinux-release package is from a previous update, you might see a transaction error such as the following:
Transaction Check Error:
file /etc/pki/rpm-gpg/RPM-GPG-KEY from install of
rhn-client-tools-1.0.0.1-18.0.2.el6.noarch conflicts with file from package
oraclelinux-release-6:6Server-5.0.2.x86_64
To avoid this error, install both the oraclelinux-release and rhn-client-tools packages from this update (oraclelinux-release-6Server-6.0.2 or later and rhn-client-tools-1.0.0.1-18.0.2 or later).

OK，我们来更新下系统先：

[root@200-70 ~]# rpm -qa |grep rhn-client
rhn-client-tools-1.0.0.1-18.0.2.el6.noarch

[root@200-70 ~]# yum groupinstall "Desktop"
（略）
