sudo command does not work in remote session to Linux machine


I am running linux commands from powershell. Made a connection from powershell to linux vm. it is working properly but when I use sudo command ( for ex . sudo useradd test) , it gives below error "sudo: sorry, you must have a tty to run sudo bash: could: command not found" .
I need to use sudo because I am not executing the script as 'root'. I need to execute this as a user.

sudo requires an interactive session. not sure what you are trying to do, but yours does not seem to be an interactive session which is why your connection is not allocated a TTY/PTS

It might be simpler to address what it is you are looking to do, and then work through to a solution that will achieve what you want with the methodology you are using.
to run sudo bash (sudo -i or sudo -s) it tells you that you have to have an established sessionv
sudo bash (sudo -i or sudo -s) envokes a shell, a shell needs a session.
sudo /usr/bin/useradd -----

there are many ways to execture a script remotely without the need to invoke a shell.

You can always use Putty instead of Powershell.

What arnold is suggesting is to try sudo -i $command or sudo -s $command (add -i + -s option) to determine if one of these options will circumvent problem you're seeing.

So the solution is... try each command + use the one that works.
There may be an option on the Powershell command to start a tty, similar to the "-t" option on ssh.
Try ssh -t to force an interactive session.

Solution is to edit the sudoers file. There is a Default "requiretty". Just comment this out and you're done

so - "visudo" to edit sudoers file as root

search for:
Defaults    requiretty

change to:
#Defaults    requiretty
