我的专用服务器运行在Centos 6.7上 百胜似乎根本没有工作。无论我尝试使用Yum安装哪个软件包，都无法使用无包“xyx”并且没有任何错误。Centos 6.7百胜没有错误
如何将整个yum重置为默认值。
我试着用
yum update
和
yum clean all
没有什么作品。
例如：当我尝试安装一个包时。
[email protected] [~]# sudo yum install -y tigervnc-server
Setting up Install Process
No package tigervnc-server available.
Error: Nothing to do
[email protected] [~]# subscription-manager list
-bash: subscription-manager: command not found
[email protected] [~]# yum search tigervnc-server
No Matches found
例子：当我尝试当我输入
[email protected] [~]# yum repolist
repo id repo name status
base CentOS-6 - Base 1,068+103
epel Extra Packages for Enterprise Linux 6 - i386 9,199+710
extras CentOS-6 - Extras 40
updates CentOS-6 - Updates 1,068+103
repolist: 11,375
我基本上要安装的桌面环境，比如GNOME，这样我可以控制主机租用服务器更新百胜
[email protected] [~]# yum update

You could try using --skip-broken to work around the problem
You could try running: rpm -Va --nofiles --nodigest
