How to redo a task?

I am new to the tasks. My task was to create a nologin user

I did :

useradd -s /sbin/nologin

It still failed.!?

How can I reattempt it! Even though I know I did it correctly.


These tasks will be reassigned to you in near future so in the mean time enjoy upcoming tasks.

Thanks, but how can I make the failed task as success? I am not liking the “failed” thing coming up even though my solution is correct.
Can you update that @Inderpreet ?
