问题:

平台:Ubuntu12.04

W: Failed to fetch http://us.archive.ubuntu.com/ubuntu/dists/precise/universe/binary-i386/Packages 404 Not Found [IP: 91.189.92.182 80]
E: Some index files failed to download. They have been ignored, or old ones used instead.

分析:

在安装系统的时候,代理服务器填写错误。

解决:

创建或编辑/etc/apt/apt.conf文件

sudo vi /etc/apt/apt.conf
添加如下内容:
Acquire::http { Proxy "http://192.168.88.10:3142"; };

Acquire::http::Proxy "http://192.168.88.10:3142";

注:代理服务器可不填写,即把该文件清空;代理服务器填写请根据实际情况填写,以上为本人的个人情况而已。
