Problem with Updating ubuntu 12.10

[plucky]

Do you have an application called Software & Updates or Software Sources in the Dash?

Cannot remember what 12.10 used.

If so,try to open one of them.

If Software Sources opens,you can change the server there.

Or

You could from a terminal

sudo rm -rf /var/lib/apt/lists/*

sudo mv /etc/apt/sources.list /etc/apt/sources.list.old

The second command renames the file sources.list to sources.list.old

and then go Here and recreate another sources.list that uses the main repository and copy it into the /etc/apt/ directory.

Good Luck

cp /etc/apt/sources.list /etc/apt/sources.old
sed -i -e 's|\(http[s]*://\)[a-z]*.\(.*\.ubuntu\.com\)|\1\2|' /etc/apt/sources.list
sudo apt-get update

Dear My Friends
Hi

Practically, I got familiar with the tasks that I should do to get rid of this ridiculous problem.
At the moment, I am at this step:

recreate another sources.list that uses the main repository and copy it into the /etc/apt/ directory. 

I have recreated another sources.list from the ubuntu sources list generator site , But How can I copy it into /etc/apt directory? My problem is now with the following line in the site:

Replace your /etc/apt/sources.list with the following one 

I tried to open the sources.list.old file and copy the items from the site in it. How ever, I confronted this error:

There is no application installed for backup file files 

Many Thnks for your earlier kind helps and would you plz help me now?

Thanks for ur codes buddy, when I tried the first command I got this error:

babak@babak-System:~$ sudo cp /etc/apt/sources.list /etc/apt/sources.list.old
[sudo] password for babak: 
cp: cannot stat `/etc/apt/sources.list': No such file or directory

But How can I copy it into /etc/apt directory?

Edit the file with

gksudo gedit /etc/apt/sources.list

and then copy and paste the output from the source list generator into the file.Then save it.

You should now be able to run

sudo apt-get update

and see if you still get the error.

Also you might have to run the rm command to delete the broken .list file if you haven't done so before.

I tried to open the sources.list.old file and copy the items from the site in it.

The sources.list.old file is just a backup incase you are unable to recreate a new sources.list file.

You have to now create a new sources.list file

Good Luck

[sudo] password for babak: 
cp: cannot stat `/etc/apt/sources.list': No such file or directory

that's because you moved it to /etc/apt/sources.list.old

instead run

sudo cp /etc/apt/sources.list.old /etc/apt/sources.list
sudo sed -i -e 's|\(http[s]*://\)[a-z]*.\(.*\.ubuntu\.com\)|\1\2|' /etc/apt/sources.list
sudo apt-get update
