Non interactive user task failed

user is added not in stapp02 but the result is failed.
Can anyone help with the issue?

Hello Agupta2,

Please login to the server as mentioned in question.
Run the below command.
useradd -s /sbin/nologin ravi

In above screenshot, first you have added the user and after that you are trying to run the command
adduser ravi -s /sbin/nologin
also, it is saying that user is already exist.
And, might be you have submitted the task and it got failed.

So, next time, before finish the task, please ensure that you have done all the steps as mentioned in question and cross-checked once whatever you done.
