yum安装DHCP服务时输出

这两种情况下都有报错信息
ERROR:dbus.proxies:Introspect error on :1.107:/org/freedesktop/PackageKit: dbus.exceptions.DBusException: org.freedesktop.DBus.Error.NoReply: Did not receive a reply. Possible causes include: the remote application did not send a reply, the message bus security policy blocked the reply, the reply timeout expired, or the network connection was broken.

原因分析：
因为是两台不同的机器同时指向同一个YUM源，其中一台机器已经通过yum install xx -y命令成功安装所需软件，而另外一台却不行，可以排除不是YUM源的问题，也不是网络的问题，那肯定是本机的问题了，
查看日志发现PackageKit这个词频繁出现，所以目标定位在这个PackageKit上面，查阅得知PackageKit是一款新的Linux包管理器，但是既然这边包这个错误，删除之是否可行？
解决办法：
yum remove PackageKit* -y //删除该管理器
