Red Hat YUM Already Running

Problem

You receive an error message, Patch scan/deployment operation failed because the YUM/DNF package manager is currently in use by the process {process_name} with process ID {process_id}, while installing the patches or scanning the systems on your network computers using Patch Manager Plus.

Cause

The following are the possible reasons:

1. The yumbackend.py process, i.e., the automatic updates for RedHat, could be running.
2. The user might have initiated a software installation at his end.
3. The user could have run commands based on yum.
4. A patch scan or deployment via Patch Manager Plus could already be using yum.

Resolution

The following steps will help in resolution:

1. Check the {process_name} and {process_id} mentioned in the error message.
2. Verify if the process is currently running:
   • Use the following command:
     ps -p <process_id>
   • If it is running:
     • Wait for the process to finish, or terminate it with caution (as this may impact its parent process).
     • To forcefully terminate the process (only if absolutely necessary), use:
       kill -9 <process_id>
3. Verify there are no active processes holding the yum tool:
   • Use the command below to check if any instance of yum is currently running:
     ps aux | grep yum
4. Check if the `/var/run/yum.pid` file exists and contains process details. If it does, it likely indicates an active `yum` operation. In that case, wait for it to finish or safely terminate the process if needed.
5. In the case of automatic updates, follow steps to disable Auto updates.
