Here is my /etc/apt/source.list file. I get many problems in the output of sudo apt-get update:

$ sudo apt-get update

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

I have several errors at the end of the output. How can I solve the problems?

Thanks!

If it is still a problem I can summarize all in answer. Just let me know. Good luck! – c0rp Apr 05 '14 at 14:57
Thanks. I updated the output, and the remaining is what I still don't know how to solve. – Tim Apr 05 '14 at 15:10
Exactly which is the problem right now? – Braiam Apr 05 '14 at 19:44
Search for "Err" and "fail" in the output, @Braiam – Tim Apr 05 '14 at 19:49
Please edit your output and narrow it down. Each "Err" depending the reason are solved differently – Braiam Apr 05 '14 at 20:01
