I really can not understand why you have this kind of settings in your sources.list
As far as I know the correct one should look something like this:
Code
- deb http://debian.mirrors.ovh.net/debian/ wheezy main contrib non-free
- deb-src http://debian.mirrors.ovh.net/debian/ wheezy main contrib non-free
- deb http://security.debian.org/ wheezy/updates main contrib non-free
- deb-src http://security.debian.org/ wheezy/updates main contrib non-free
- # wheezy-updates, previously known as 'volatile'
- deb http://debian.mirrors.ovh.net/debian/ wheezy-updates main contrib non-free
- deb-src http://debian.mirrors.ovh.net/debian/ wheezy-updates main contrib non-free
But I really don't know if you need sid packages for your setup. You have to check yourself.
