如何在Ubuntu 14.04

Question

上安裝nodejs 4. *我一直在尋找一些解釋如何在Ubuntu 14.04上安裝nodejs 4. *的網頁，但它並沒有安裝，並告訴我我已經有了最新版本：

$ curl -sL https://deb.nodesource.com/setup_4.x | sudo -E bash - 

## Installing the NodeSource Node.js v4.x LTS Argon repo... 


## Populating apt-get cache...

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

$ sudo apt-get install nodejs

$ node --version 
v0.10.25 

有一個在curl命令的最後一個錯誤，但我不知道這是否」有關。我遵循本指南 - https://nodejs.org/en/download/package-manager/ - 但其他網頁似乎是相同的。怎麼了？
