Build probably depends on expired links

[andredelft]

When trying to build the image, I get the following messages in the console:

W: Failed to fetch http://deb.debian.org/debian/dists/wheezy/main/binary-amd64/Packages  404  Not Found

W: Failed to fetch http://deb.debian.org/debian/dists/wheezy-updates/main/binary-amd64/Packages  404  Not Found

W: Failed to fetch http://deb.debian.org/debian/dists/wheezy-backports/main/binary-amd64/Packages  404  Not Found

W: Failed to fetch http://security.debian.org/debian-security/dists/wheezy/updates/main/binary-amd64/Packages  404  Not Found

I suspect these links are expired by now.
