安装 cockpit使用yum工具出错This system is not registered with an entitlement server. You can use subscription-manager to register.

下午安装 cockpit 时，使用 yum 工具的时候哦，出现如下信息：

This system is not registered with an entitlement server. You can use subscription-manager to register.

尽管不影响centos 的使用，安装软件也没有任何的影响。但是也是想知道其中的原因；下面是在国外论坛上对于centos 的讨论。

问题：

Installing Cockpit on CentOS7 adds the following nag/notice - seen every time you use yum update etc.:

"This system is not registered with Subscription Management. You can use subscription-manager to register"

Removing the cockpit-subscriptions - breaks the web interface fuctionality - You can log in but then you get an error page.

Does anyone have a fix for this?
Obviously, this is designed for RHEL but, seems the CentOS package shouldn't have this "Feature".

答案1：

Unfortunately cockpit requires subscription-manager and that causes that message to be emitted by yum. However it is only an informational message, not an error and everything works just as it did.

答案2：

Seems simple to nuke the subscription nag by editing /etc/yum/pluginconf.d/subscription-manager.conf :

[main]
enabled=0

Thanks TrevorH

答案3：

I could solve the problem by setting enabled=0 in [main] section of /etc/yum/pluginconf.d/enabled_repos_upload.conf configuration file:

[main]
enabled=0
supress_debug=False
supress_errors=False
