Introduction:<\/h2>\n

Yum is a package management utility used in many Linux distributions to install, update, and remove software packages. Occasionally, when you try to use yum, you may get an error message that says \u201cAnother app is currently holding the yum lock; waiting for it to exit\u201d. This error occurs when another process is currently using yum, and the lock file is preventing other processes from using yum.<\/p>\n

Existing lock \/var\/run\/yum.pid: another copy is running as pid [pid number].\r\nAnother app is currently holding the yum lock; waiting for it to exit...\r\n<\/pre>\n
or<\/p>\n
[root@server \/]# yum install [service name]\r\nLoaded plugins: fastestmirror\r\nExisting lock \/var\/run\/yum.pid: another copy is running as pid 20360.\r\nAnother app is currently holding the yum lock; waiting for it to exit...\r\n  The other application is: yum\r\n    Memory :  19 M RSS (396 MB VSZ)\r\n    Started: Sun Mar  6 21:06:51 2011 - 00:29 ago\r\n    State  : Traced\/Stopped, pid: 20360\r\n<\/pre>\n
In this guide, we will show you how to resolve this error.<\/p>\n

Step 1: Check yum processes<\/h2>\n
The first step is to check if any processes are currently using yum. You can do this by running the following command:<\/p>\n
ps aux | grep yum\r\n<\/pre>\n
This will display a list of processes that are currently using yum.<\/p>\n
Step 2: Kill yum processes<\/h2>\n
If you find any processes that are using yum, you need to terminate them before you can use yum. You can do this by running the following command:<\/p>\n
sudo kill PID<\/i>\r\n<\/pre>\n
Replace\u00a0PID<\/i>\u00a0with the process ID of the yum process you want to terminate. You may need to use the kill -9 option if the process does not terminate gracefully:<\/p>\n
sudo kill -9 PID<\/i>\r\n<\/pre>\n
Step 3: Remove yum lock file<\/h2>\n
After terminating the yum process, you need to remove the lock file to allow other processes to use yum. You can do this by running the following command:<\/p>\n
sudo rm \/var\/run\/yum.pid\r\n<\/pre>\n
This will remove the yum lock file.<\/p>\n

Step 4: Verify yum availability<\/h2>\n
Finally, you can verify that yum is now available by running a yum command:<\/p>\n
yum check-update\r\n<\/pre>\n
If yum is working correctly, you should see a list of available updates.<\/p>\n
