Hi Aditi,

The place to ask question is now on answers.ros.org, so It is more easaly to
filter and search into database. Please ask a question there,  tag this as
"installation" and "debian" and send me in private the link to your
question, I'll look at it. I have a working Debian installation so you
should end in success.
 Thanks
