I am getting Duplicate sources.list entry exception every time i perform an update or install operation on my Ubuntu server.

W: Duplicate sources.list entry http://debian.datastax.com/community/
stable/main amd64 Packages
(/var/lib/apt/lists/debian.datastax.com_community_dists_stable_main_binary-amd64_Packages)
W: Duplicate sources.list entry http://debian.datastax.com/community/
stable/main i386 Packages
(/var/lib/apt/lists/debian.datastax.com_community_dists_stable_main_binary-i386_Packages)
W: You may want to run apt-get update to correct these problems

I am seen some similar posts over internet, still unable to resolve that.

Here is my sources.list content

  • Upload your /etc/apt/sources.list and all files in /etc/apt/sources.list.d/ to http://paste.ubuntu.com and include their links in your question. – Eric Carvalho May 24 '13 at 17:55
