Duplicate sources.list entry
 

Hi

When I run apt-get update I receive this warning message:
W: Duplicate sources.list entry http://repository.spotify.com/ stable/non-free amd64 Packages (/var/lib/apt/lists/repository.spotify.com_dists_stable_non-free_binary-amd64_Packages)
W: Duplicate sources.list entry http://repository.spotify.com/ stable/non-free i386 Packages (/var/lib/apt/lists/repository.spotify.com_dists_stable_non-free_binary-i386_Packages)
W: You may want to run apt-get update to correct these problems

I ran apt-get update agen but it did not help. I also ran /etc/apt/sources.list.d/

ls /etc/apt/sources.list.d/:

cat /etc/apt/sources.list.d/

cat /etc/apt/sources.list.d/spotify

but can not get a list of Duplicate sources is there a command that will work. I am running xubuntu 15.04 if that makes a difference. I trid y ppa manager to see it was a ppa problem but no Duplicates there. I do not see a problem in the system but spotify does not work. Thanks

Can you post the contents of your /etc/apt/sources.list file.
jdk

This is what I get on all command lines so far sudo: /etc/apt/sources.list: command not found

What did you type? "sudo /etc/apt/sources.list"? That won't do it. You just tried to execute a text file.

You want to see the contents of the file. Use the "cat" command. This reads the contents of the file and prints them to the screen.

I typed (sudo /etc/apt/sources.list file.jdk). And this is what I get with (sudo cat /etc/apt/sources.list)

maybe this will help.Thanks

Good. Now you can run this command from a terminal and post the output:
jdk

Line (sudo ls /etc/apt/sources.list.d/)

appgrid-ubuntu-stable-vivid.list google-earth.list paolorotolo-ubuntu-android-studio-vivid.list.save ubuntu-wine-ubuntu-ppa-vivid.list webupd8team-ubuntu-y-ppa-manager-vivid.list.save
google-chrome.list google-earth.list.save spotify.list ubuntu-wine-ubuntu-ppa-vivid.list.save xorg-edgers-ubuntu-ppa-vivid.list
google-chrome.list.save paolorotolo-ubuntu-android-studio-vivid.list spotify.list.save webupd8team-ubuntu-y-ppa-manager-vivid.list xorg-edgers-ubuntu-ppa-vivid.list.save

Thanks whats next?

I notice you have spotify repos listed in both sources.list and in the sources.list.d folder. Try commenting out the spotify repos in your sources.list file. Just put a hash sign "#" in front of the lines with the spotify repository as shown below.
This is what you have now. Change the line to this:
Remember you have to edit the sources.list file as root or by using sudo. See if this makes the warning messages go away.
jdk

Ok how and where do I go to edit this?

You just edit it with any text editor. It's just a plain text file.

Note that you should prefix the command with "sudo" so that it gets run as root and that it has permission to actually write to the file

Thanks to all of you for all the help! Thanks
