This question already has an answer here:

I have Ubuntu 13.10 installed as a dual boot system with Windows 7. Ubuntu loads normally, but when I try to update with Synaptic Package Manager, I get the following error message and the system stops there....

Failed to fetch  
Failed to fetch

(and other links listed too!)

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

What is wrong please?

I agree: I think that answer should solve this (or problems like it for others who find this question by searching). –  Eliah Kagan Sep 29 '14 at 4:25

You should check your source file config : /etc/apt/sources.list

This website will also help you generate a sources.list :

To better understand what can be the problem check your log files : /var/log/dpkg.log also /var/log/apt

Very many thanks for your help. I edited the sources.list and this seems to have sorted the problem. Thanks again. –  user226737 Dec 18 '13 at 19:06

This means that those mirrors are down for the moment (or permanently). You should replace them with good mirrors (ie. removing the part will get you a good mirror) or replace them entirely with your own preferred mirror.
