Installation failure with curl - `stty: stdin isn't a terminal`

[DataEnggNerd]

While installing through curl -L yen.tushar.lol/install.sh | s the while loop for giving y|n is running infinitely.

Note: When I have cloned the shell script to local and executed, worked without a problem.

I faced this yesterday, so I think I can reproduce this and find out the root cause.

It worked just fine on my other, identical machine, which is weird.
