Concern over apt-get messagefrom PVE repository on updating 3.1 install

Here is my /etc/apt/sources.list file entries:

deb http://ftp.us.debian.org/debian wheezy main contrib non-free
deb-src http://ftp.us.debian.org/debian wheezy main contrib non-free


# PVE packages provided by proxmox.com for non-subscription Proxmox VE 3.x
deb http://download.proxmox.com/debian wheezy pve-no-subscription

# security updates
deb http://security.debian.org/ wheezy/updates main contrib

#clean http://ftp.us.debian.org/debian


But when I run the up-date command I get this problem with it trying to go to the subscription area, I think:


# apt-get update && apt-get dist-upgrade

E: Some index files failed to download. They have been ignored, or old ones used instead.

Can anyone tell me what may be going on? Isn't this where I am supposed to look for pve-no-subscription ?

Thanks for any help you can offer.
