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

I noticed that the iso download from a Chinese mirror server, So I try use proxy to download from kali linux server, but the problem still exists.I had add the Kali Rolling Repository on http://docs.kali.org/general-use/kali-linux-sources-list-repositories.
