What is the first step to take when troubleshooting a failed action to update an operating system across multiple machines?

The correct first step when troubleshooting a failed action to update an operating system across multiple machines is to check the logs of the failed action. The logs provide detailed information about what happened during the execution of the action and can help identify specific errors or issues that occurred. By reviewing the logs, you can pinpoint whether the failure was due to a problem with the action's configuration, network issues, client-related problems, or other factors. This information is crucial for diagnosing the problem accurately and effectively.

Initiating troubleshooting through logs is essential, as it enables you to gather relevant data before taking further steps, such as checking network connectivity or reinstating clients. Understanding the context of the failure from the logs can lead to a quicker resolution and more informed subsequent actions.
