Yum installation ERROR: Failed. proxies

Problem:
Run
Installed products updated.

The following error is reported:
ERROR: failed. proxies: Introspect error on: 1.261:/org/freedesktop/PackageKit: plugin. exceptions. DBusException: org. freedesktop. invalid. 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.
Unable to send message to PackageKit

Troubleshooting:

Because two different machines direct to the same YUM source at the same time, one of them has successfully installed the required software through the yum install xx-y command, but the other one does not, it can be ruled out that the problem is not a YUM source or a network problem. It must be a local problem,
Check the log and find that the word PackageKit frequently appears. Therefore, the target is located on this PackageKit. Check that PackageKit is a new Linux package manager, but since this package is incorrect, is deletion feasible?

Problem Solving
Yum remove PackageKit *-y // Delete this manager
