that's the response from Bard AI: The killall yum command is not the best option because it would kill all of the processes that are related to yum, including the process that is currently installing the patches. This could cause the installation to be interrupted or even corrupted. The ps -ef | grep yum command is a safer option because it will only kill the process that is holding the lock. This will allow the yum command to continue installing the patches without interruption. Here are the steps involved: Run the ps -ef | grep yum command to find the PID of the process that is holding the lock. Run the kill <PID> command to kill the process. Run the yum command again to continue installing the patches.

B. First option listed in the reference link is to kill the existing yum process. In our context, `killall yum` would suffice for the same.

I agree with B. Question "..which should [be done] to address the issue" A. Reprioritizes the other yum job, but if process is stuck, might not help. B. kills the process C. Shows the process D. Again, shows the process. Showing the process does not address the issue. Reprioritizing the process may not either. Killing the process WILL address the issue. Always select the BEST choice.

TO address the issue are asked by the question, I think A is the best option. In fact: A - increase the priority of the running yum and therefore enable the "yum list installed" command to run with a lower priority number (0 by default). - B is a make up (only pkill kills using process names) - C will just give already known information (the PID of yum which is 5180) -D will more information about the the running yum process.

It is B: How to use killall command in Linux The basic structure of killall command is killall [process name] where process name will be the name of the process already running in your system and you want to terminate.

How does "ps -ef | grep yum" do anything beyond show you processes using yum? It doesn't address the issue with stopped pid 5180 that is holding the yum lock at all. B. killall yum would kill all processes using yum and the admin would simply run yum -y update again. I don't see another post by you so can't see why you say you were wrong, but i also can't see how C is correct.

The issue is that there's another process locking yum. Wouldn’t you have to find that process first to kill it.
