Ubuntu ARM更改为国内源

写在前面
这几次写博客客都是有很大的戾气！
算了，认真做事，认真记录吧。要乐观一点少年。
arm ubuntu开发板的apt的库和普通ubuntu的库是不一样的，arm的是ubuntu-ports库。
百度也是垃圾，搜半天也搜不到一个说阿里源的ubuntu-ports的设置方法。
之前用USTC中科大的ubuntu-ports，不知道咋回事，apt-get update后一直卡在0%working，晕。简单来说，就是你要换一个源了，我不知道是这个源有问题，还是我开发板有问题，还是线路有问题。。。
其实你发现，很多镜像网站，都只有ubuntu源的设置说明，没有ubuntu-ports的设置说明。只有USTC都有，然而我用不了。
正文
阿里云镜像网站：https://opsx.alibaba.com/mirror
里面有ubuntu源的设置说明
以ubuntu16.04为例：
ubuntu 16.04 配置如下
ubuntu 16.04 配置如下 deb http://mirrors.aliyun.com/ubuntu/ xenial main deb-src http://mirrors.aliyun.com/ubuntu/ xenial main deb http://mirrors.aliyun.com/ubuntu/ xenial-updates main deb-src http://mirrors.aliyun.com/ubuntu/ xenial-updates main deb http://mirrors.aliyun.com/ubuntu/ xenial universe deb-src http://mirrors.aliyun.com/ubuntu/ xenial universe deb http://mirrors.aliyun.com/ubuntu/ xenial-updates universe deb-src http://mirrors.aliyun.com/ubuntu/ xenial-updates universe deb http://mirrors.aliyun.com/ubuntu/ xenial-security main deb-src http://mirrors.aliyun.com/ubuntu/ xenial-security main deb http://mirrors.aliyun.com/ubuntu/ xenial-security universe deb-src http://mirrors.aliyun.com/ubuntu/ xenial-security universe
所以只要将ubuntu改成ubuntu-ports即可，这是我观察USTC的设置说明总结的，已经在我的板子上实验成功。
ubuntu 16.04 for arm 配置如下:
ubuntu 16.04 配置如下 deb http://mirrors.aliyun.com/ubuntu-ports/ xenial main deb-src http://mirrors.aliyun.com/ubuntu-ports/ xenial main deb http://mirrors.aliyun.com/ubuntu-ports/ xenial-updates main deb-src http://mirrors.aliyun.com/ubuntu-ports/ xenial-updates main deb http://mirrors.aliyun.com/ubuntu-ports/ xenial universe deb-src http://mirrors.aliyun.com/ubuntu-ports/ xenial universe deb http://mirrors.aliyun.com/ubuntu-ports/ xenial-updates universe deb-src http://mirrors.aliyun.com/ubuntu-ports/ xenial-updates universe deb http://mirrors.aliyun.com/ubuntu-ports/ xenial-security main deb-src http://mirrors.aliyun.com/ubuntu-ports/ xenial-security main deb http://mirrors.aliyun.com/ubuntu-ports/ xenial-security universe deb-src http://mirrors.aliyun.com/ubuntu-ports/ xenial-security universe
你也可以同样的方法去改其它的镜像网站的源。
搞之前，别忘了把自带的源给备份一下，稳妥一点嘛！
2019.7.6 更新
对于ubuntu 18.04的ARM
