Can someone provide a real, correct and genuine sources.list for Ubuntu 15.04?

Question

I have been using Ubuntu for a while now and I have been having all problems that I needed not to post a thread for to get answers, until I recently upgraded to Ubuntu Vivid.

Ubuntu is great but each time I run sudo apt-get update I have a smooth run of update which return a notice of a duplicate in /var/lib/apt/lists.

That is not even where the problem lies. What is very frustrating is that even when I run the proposed update, it still produces the same result.

I was using Ubuntu 14.04 then I upgraded to Ubuntu Utopic before upgrading to Vivid.

All I need is someone to please provide a compact without duplicates source list.

Please.

Thank you all in advance.

Edit: This is the new error I got from reloading the software-properties-gtk.

W: Duplicate sources.list entry http://security.ubuntu.com/ubuntu/ vivid-security/restricted i386 Packages (/var/lib/apt/lists/security.ubuntu.com_ubuntu_dists_vivid-security_restricted_binary-i386_Packages)

Here is my virgin sources.list

Duplicates can also arise when entries are included in sources.list and in the files in the folder /etc/apt/sources.list.d.

You can remove duplicates with Y PPA Manager:

sudo add-apt-repository ppa:webupd8team/y-ppa-manager
sudo apt-get update
sudo apt-get install y-ppa-manager

Run Y PPA Manager

Select Advanced

Select Scan and remove duplicate PPAs

When this is complete, then start an update:

sudo apt-get update

This one should do (make sure to replace us with your country prefix):

deb http://us.archive.ubuntu.com/ubuntu/ vivid main universe restricted multiverse
deb-src http://us.archive.ubuntu.com/ubuntu/ vivid main universe restricted multiverse

deb http://us.archive.ubuntu.com/ubuntu/ vivid-security main universe restricted multiverse
deb-src http://us.archive.ubuntu.com/ubuntu/ vivid-security main universe restricted multiverse

deb http://us.archive.ubuntu.com/ubuntu/ vivid-updates main universe restricted multiverse
deb-src http://us.archive.ubuntu.com/ubuntu/ vivid-updates main universe restricted multiverse

If you post the content of your sources.list, maybe we can help you to spot the duplicates. It is not the whole line that needs to be exact, because each line can contain multiple repos.

[Admin]

it will not allow me to post picture or the error message because it appears to be links to the repos more than 2, cos I'm a noob

[Admin]

@MarcoOz You can post the full error message by pasting it in, selecting it, and pressing Ctrl+K (or clicking the {} tool in the editing toolbar). This formats it as code, which will make it display more correctly, and has the additional benefit that code-formatted URLs are not automatically linkified--thus it won't make your post have more than two links in it. As for a screenshot, I highly recommend posting the text of the error message but if you wish to post an image you can upload it somewhere like postimage.org or imgur.com, give the link, and someone can add it.

I want to thank everybody that took the time to look at this problem I am having. I want to say that I have taken the time to follow step by step of the provided guidances but still my sudo apt-get update brings the Dupes notice. Could it be just me or this a serious bug in the new release?

[A.B.]

@MarcoOz Do not thank me, give me an upvote :)

[A.B.]

@MarcoOz Maybe you have duplicate along with the files in this folder: "/etc/apt/sources.list.d"

[Mr One ZED]

A.B. I looked through that folder but there is nothing like that. All the files there are all of the same order. For instance, google-chrome.list, google-chrome.list.distupgrade, google-chrome.list.save and all in that order for all files. Noe repetitions.

[A.B.]

@MarcoOz Another idea. I'll update my answer.

[Mr One ZED]

Improved? Where is the improved answer ;)

[A.B.]

@MarcoOz The part with the "Y PPA Manager"

[Mr One ZED]

I have just finished doing that and it found 3 duplicates which I removed. Sadly, I got the same duplicate bug when I run sudo pat-get update but this time some notices about NO_PUBKEY for several others. How come?

[A.B.]

@MarcoOz In Y-PPA-Manager is an option "Advanced > Try to import all missing GPG keys".

[A.B.]

@MarcoOz Move your entire files from /etc/apt/sources.list.d in a backup directory. Then apt-get update. Then copy every single file with the extension "list" back. And run every time "apt-get update". Then the error should occur sometime back and you know in which file is the problem.

[Mr One ZED]

This is the new error I got from reloading the software-properties-gtk

[A.B.]

@MarcoOz Where is the error?

[Mr One ZED]

Trying to post it here but I was told I can't post more than 2 links cos I need at least 10 reputation. So I wonder how I'm gonna be able to make anyone know what the heck of a problem I am facing using my ubuntu vivid. And posting the error text here won't allow due to limited character spaces.......Really?

[A.B.]

Update your Question. Add the error message. That should be possible.

[Mr One ZED]

If fact i am typing this comments in a new tap and left the other one in which I am trying to update my original post with. It says I can't post a picture, yet. Well hell with that and then I try to ignore the pic and input just the error message but the repos sources appear to be links, so you see how that goes for me.

[A.B.]

@MarcoOz Mark the error message as code
