How do I restore the default repositories?
There are now errors when updating and I cannot install most software due to a corrupted
/etc/apt/sources.list
file. Is there a copy I can download to replace it?
The file would be for Ubuntu 12.04 (Final Beta) in the United States.

Have you tried the "Software Sources" GUI app? I'm not running 12.04, but in the past, this is where you could choose the repository location, and edit which ones to use from that location.

I did, and none of the errors listed were in that. I just want to find a copy of the sources.list file as it was when I had freshly installed Ubuntu.

You should be able to go to the "Other Software" tab, and delete the duplicate entries. Or, if you're not sure, you can uncheck a few and see if that fixes the problem. Also, did you run "sudo apt-get update" like it suggested?

All of the ones with ppa.launchpad.net should be listed in the "Other Software" tab, and can be disabled or deleted. In fact, I believe all of the ones with http:// URLs could be disabled, and would be lost if you replace the file with the default. If you go to "ppa.launchpad.net, you will see a big list, which includes things like "pmcenery"; I followed it to ppa/ubuntu/dists and saw that the last version was natty, so there is no oneiric or precise to be had. That is why you are getting the 404 (not found) error.

You can use this trick. Open a terminal ( Pressing Ctrl+Alt+T ) and do these
Move the corrupted one to the safe place
sudo mv /etc/apt/sources.list ~/
and recreate it
sudo touch /etc/apt/sources.list
Open Software & Updates
software-properties-gtk
This will open
software-properties-gtkwith no repository selected.
Then change the server to Main server or to any other server of your choice. You must enable some repositories from the new window in order to create new sources.list file in /etc/apt/.
After enabling some sources from Ubuntu software tab, you can enable the updates. To do so, switch to Updates tab and select one or more updates channel. I recommend selecting security and updates channel at least. (This image is later added from Ubuntu xenial, so there can be some differences)
Updated with inline content
This is the sources.list file for 12.04 Precise Pangolin. If you're using other release, you need to replace the precise word with your ubuntu release name. You can see the which name you should use with this command
lsb_release -c -s
And to replace the word you can use this sed command (assuming you copied the sources content in /etc/apt/sources.list
sudo sed -i "s/precise/$(lsb_release -c -s)/" /etc/apt/sources.list
Now, content of sources.list with main ubuntu mirror

Go to https://repogen.simplylinux.ch.
Select your Country and Ubuntu Release.
For the default set of repositories, you need to enable these repositories.
- All of the Ubuntu Branches repositories.
- Security - Important Security Updates.
- Security Sources Repository
- Updates - Recommended Updates
- Updates Sources Repository
If you want to install software from Canonical Partner Repositories (closed source software), enable the Ubuntu Partner Repositories (both of them).
Enable any 3rd party repository you wish to enable.
Now, click the Generate List button at the bottom of that page and you'll see your generated sources.list.
Replace the old sources.list with the new one
Run the following commands in a Terminal.
sudo mv /etc/apt/sources.list /etc/apt/sources.list.old
gksudo gedit /etc/apt/sources.list
Copy/paste all the text from the newly generated sources.list to this file. Save it and close Gedit.
Now, update apt.
sudo apt-get update
This will update your repository index with the current sources.list and then you can install any software using Software Center, Synaptic or apt-get.

Somewhere in the past, you added ppa.launchpad.net/pmcenery/ppa/ubuntu/dists/precise/main/source/… to your list. Did you last have the natty version before the beta? I suspect the upgrader changed natty to precise, but there is no precise version available for this package. I would delete it from "Other Software". The error isn't hurting anything, by the way.

By default there will be a backup for your sources.list file on the same directory itself.
sudo cp /etc/apt/sources.list.save /etc/apt/sources.list

You can use this trick. Open a terminal ( Pressing Ctrl+Alt+T ) and do these
Move the corrupted one to the safe place
sudo mv /etc/apt/sources.list ~/
and recreate it
sudo touch /etc/apt/sources.list
Open Software & Updates
software-properties-gtk
This will open
software-properties-gtkwith no repository selected.
Then change the server to Main server or to any other server of your choice. You must enable some repositories from the new window in order to create new sources.list file in /etc/apt/.
After enabling some sources from Ubuntu software tab, you can enable the updates. To do so, switch to Updates tab and select one or more updates channel. I recommend selecting security and updates channel at least. (This image is later added from Ubuntu xenial, so there can be some differences)
Updated with inline content
This is the sources.list file for 12.04 Precise Pangolin. If you're using other release, you need to replace the precise word with your ubuntu release name. You can see the which name you should use with this command
lsb_release -c -s
And to replace the word you can use this sed command (assuming you copied the sources content in /etc/apt/sources.list
sudo sed -i "s/precise/$(lsb_release -c -s)/" /etc/apt/sources.list
Now, content of sources.list with main ubuntu mirror

Go to https://repogen.simplylinux.ch.
Select your Country and Ubuntu Release.
For the default set of repositories, you need to enable these repositories.
- All of the Ubuntu Branches repositories.
- Security - Important Security Updates.
- Security Sources Repository
- Updates - Recommended Updates
- Updates Sources Repository
If you want to install software from Canonical Partner Repositories (closed source software), enable the Ubuntu Partner Repositories (both of them).
Enable any 3rd party repository you wish to enable.
Now, click the Generate List button at the bottom of that page and you'll see your generated sources.list.
Replace the old sources.list with the new one
Run the following commands in a Terminal.
sudo mv /etc/apt/sources.list /etc/apt/sources.list.old
gksudo gedit /etc/apt/sources.list
Copy/paste all the text from the newly generated sources.list to this file. Save it and close Gedit.
Now, update apt.
sudo apt-get update
This will update your repository index with the current sources.list and then you can install any software using Software Center, Synaptic or apt-get.

Somewhere in the past, you added ppa.launchpad.net/pmcenery/ppa/ubuntu/dists/precise/main/source/… to your list. Did you last have the natty version before the beta? I suspect the upgrader changed natty to precise, but there is no precise version available for this package. I would delete it from "Other Software". The error isn't hurting anything, by the way.

By default there will be a backup for your sources.list file on the same directory itself.

Thank you for your interest in this question.
Because it has attracted low-quality or spam answers that had to be removed, posting an answer now requires 10 reputation on this site (the association bonus does not count).
Would you like to answer one of these unanswered questions instead?
Have you tried the "Software Sources" GUI app? I'm not running 12.04, but in the past, this is where you could choose the repository location, and edit which ones to use from that location.

I did, and none of the errors listed were in that. I just want to find a copy of the sources.list file as it was when I had freshly installed Ubuntu.

You should be able to go to the "Other Software" tab, and delete the duplicate entries. Or, if you're not sure, you can uncheck a few and see if that fixes the problem. Also, did you run "sudo apt-get update" like it suggested?
– Marty Fried
Apr 21 '12 at 18:34
Yes, I did. It gives me

All of the ones with ppa.launchpad.net should be listed in the "Other Software" tab, and can be disabled or deleted. In fact, I believe all of the ones with http:// URLs could be disabled, and would be lost if you replace the file with the default. If you go to "ppa.launchpad.net, you will see a big list, which includes things like "pmcenery"; I followed it to ppa/ubuntu/dists and saw that the last version was natty, so there is no oneiric or precise to be had. That is why you are getting the 404 (not found) error.
