我试图在我的centos 7中安装RDO存储库但是我收到以下错误
# yum install -y https://rdoproject.org/repos/rdo-release.rpm
Loaded plugins: fastestmirror, langpacks
rdo-release.rpm | 5.1 kB 00:00:00
Examining /var/tmp/yum-root-lLOS4K/rdo-release.rpm: rdo-release-liberty-2.noarch
/var/tmp/yum-root-lLOS4K/rdo-release.rpm: does not update installed package.
Error: Nothing to do
有人可以帮我吗？
