Explanation:
Yum is an update manager for RedHat, Fedora, and other distibutions that use .rpm packages. The original version was written for Yellowdog Linux, so YUM originally stood for "Yellowdog Update Manager". The lock is a file or bit or byte set when a program is started to manage something, to keep another program from accessing the same resource (in this case packages).

There are few ways to solve the problem:

1) To reboot, as locks will generally be unset after a boot - as someone else mentioned, this might not be a good way if the system is a server that other people or computers are depending on, but for a personal system that's generally ok.

2) Press Ctrl-C to break and type the command: su -c 'rm /var/run/yum.pid'

3) (It looks like yum update package is running in the background., therefore..) type the command:

su -
service yum-updatesd stop
yum update
