Permission denied while installing dependencies for Nvidia Isaac SDK

Hello,
whenever i try to install the dependencies for Nvidia Isaac SDK on my Jetson Nano using the command
bob@desktop:~/isaac$ engine/build/scripts/install_dependencies_jetson.sh -u <jetson_username> -h <jetson_ip>
It asks for my password and when i wrote the password it says Permission Denied, Please try again.
Can anyone help?

Moving to Isaac SDK forum for the support.
