ubuntu更改国内镜像文件

 

用java几年，最近想了解一下Python，打算安装Ubuntu系统，Ubuntu系统安装难免遇到一些问题，再次罗列

问题：Ubuntu系统安装，前部分有部分文件和命令的下载，如果不使用国内镜像文件，下载速度非常慢，这时就需要考虑更换镜像（推荐阿里的镜像）

补充（虚拟机用vm virtualbox ）

镜像文件修改路径：vim /etc/apt/sources.list ， 如果更改之前需要做保存，可以用cp /etc/apt/sources.list /etc/apt/sources.back

后添加阿里镜像：

deb http://mirrors.aliyun.com/ubuntu/ trusty main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ trusty-security main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ trusty-updates main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ trusty-proposed main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ trusty-backports main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ trusty main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ trusty-security main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ trusty-updates main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ trusty-proposed main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ trusty-backports main restricted universe multiverse

当然，如果你想使用其他镜像，也可考虑，这里也做一下备注#网易163

可能有些同志在修改文件时出现此错误：（没有修改权限）此时的你会一脸闷逼，明明自己的角色是超级管理员（root）为啥不行。

接下来你可能需要操作此命令

经常是用vim打开了某个/etc下的文件，使用 :w 保存的时候提示 "E45: 'readonly' option is set (add ! to override)"，而 :w! 则提示 "E212: Can't open file for writing"。

    通常的解决方案是 :q!

    退出后，在命令行里输和：sudo !!

    再次vim ...编辑，

    再:/wq，就可以了。

然后更新源：

sudo apt-get update

. 更新软件

?

1	sudo apt-get update

然后你就会发现，下载更新速度，快了N倍
