Hi Jay, welcome to our community.
Which System are you trying to do it on as that could make a difference. When I looked just now there did seem, at quick glance different answers depending on that.
If you could provide that detail it would help the community to help you.
Thanks
Sir I am on my Ubuntu version 16.04 LTS. Today I installed Ubuntu Dual boot alongside windows. & Downloaded Xampp server & while installing this error comes. My Laptop is Dell Vostro 15 3568.
