    What is this error after updating: "W: Duplicate sources.list"

    Hi

    After I run Sudo apt-get update in terminal I got this at the end :


    Code:
    Reading package lists... Done
    W: Duplicate sources.list entry http://ir.archive.ubuntu.com/ubuntu/ quantal/main amd64 Packages (/var/lib/apt/lists/ir.archive.ubuntu.com_ubuntu_dists_quantal_main_binary-amd64_Packages)
    what is this error and how can I solve it?

    Regards
    Bobi

    Post the output of
    Code:
    cat /etc/apt/sources.list
    And we'll see what entries are dupes.
