Linux User non-interactive shell task failed

thor@jump_host /$ sudo useradd -s /sbin/nologin javed

We trust you have received the usual lecture from the local System
Administrator. It usually boils down to these three things:

#1) Respect the privacy of others.
#2) Think before you type.
#3) With great power comes great responsibility.

[sudo] password for thor:

Asking for root password.I don’t no the password Any body can help. I am new to Linux

Hello Sud,
I don’t believe you are required to do any task on jump_host. I think you ssh to the host you are ask to do work on as a specific user. All accounts are provided in the wiki. Read the instructions again.

[sudo] password for thor:
this is not asking for roots password. It is asking for thor’s password. When you login to the correct server, with the right user, when you do sudo, provide that users password. They are all in the wiki.

As per this task i have done every thing . but getting the below mentioned error

create a user named ravi with a non-interactive shell in the app01 server.

thor is not a user on stapp01. That is why it does not work. Below is what is listed on the wiki.
tony is the user on stapp01 and his password is Ir0nMan@n. So to login to stapp01, you will initiate it from jump_host server as such:

ssh tony@stapp01
or
ssh tony@172.16.238.10

Once logged in, then you can do the task:
sudo useradd -s /sbin/nologin javed

You will then be asked for tony’s sudo password
[sudo] password for tony:
the password will be tony’s password (Ir0nMan@n)
