树莓派Ubuntu Mate 16.04 修改为国内更新源

收藏:https://blog.csdn.net/wang_shuai_ww/article/details/80386708

更换步骤
以root身份打开 /etc/apt/sources.list ,至于用什么打开随意
将 http://ports.ubuntu.com/ 全部替换为 http://mirrors.ustc.edu.cn/ubuntu-ports/ ,这是中科大的
执行 sudo apt-get update 和 sudo apt-get upgrade 测试

查看是否提供arm支持的方法

打开一个镜像站点,然后以此打开 /dists/xenial/main/ ,看这个目录下面有没有 binary-arm 这样的字眼,如果有,就是提供arm支持的
