Natty is EOL and no longer supported in any way. It is like installing Windows 95 then trying to get updates online. There aren't any.

I recommend you wipe Natty off and clean install Precise which is LTS and supported til April 2017

I suspect you followed part of this procedure:

https://help.ubuntu.com/community/PackageManagerTroubleshootingProcedure

However, at the beginning of this procedure, I wrote the following:

"
The only supported releases of Ubuntu are the ones that are NOT End of Life (EOL) in the following table:

https://wiki.ubuntu.com/Releases

"

If you visit the following page

https://wiki.ubuntu.com/Releases

you will see that Ubuntu 11.04 is end-of-life.....
