What should I do if Linux yum prompts Loaded plugins error?

yum is the Linux software package manager, also called yum source. Sometimes a Loaded plugins error occurs and restarting has no effect. The solution to this situation is as follows.

The following error occurs when using yum in linux:

Loaded plugins: fastestmirror, security

Existing lock /var/run/yum.pid: another copy is running as pid 4733.

Another app is currently holding the yum lock; waiting for it to exit.. .

The other application is: yum-updatesd-he

Memory: 22MB RSS (249MB VSZ)

Started: Fri Jul 6 12:18:29 2012 - 53:47 ago

State: Sleeping, pid: 4733

The problem persisted after shutting down and restarting. Then I tried deleting the yum.pid file and restarting the yum service. The specific command was as follows:

rm -rf /var/run/yum.pid

/sbin/service yum-updatesd restart

The above is the editor’s summary of the solutions to the Loaded plugins error in Linux yum. If you still cannot solve the problem after shutting down and restarting, you can delete the yum.pid file to solve the problem.
