Finding difficulty in linux mkdir

Sir i have started learning linux now

The sudo password you are providing is incorrect.

Can you please explain the way of providing it

Where it is showing [sudo] password for user: provide the password that you use to log in , in your machine. It might not show the password but you just type it and press enter to confirm.

Hello @sanashravaniaug2,
Its clear that the password you have entered is incorrect. Check your Capslock status on the keyboard. Note that the password does not appear in the terminal while you type. Try to recollect the correct password if the above instructions didn’t work for you.
