ubuntu镜像源切换

滇游记

换源准备：

换源之前明确使用平台，X86架构、ARM架构的源，ubuntu18.04和unbuntu16.04等源均不同，切忌病急乱投医，看到一个源复制过来添加后没用。

分析一条源：

deb http://mirrors.tuna.tsinghua.edu.cn/ubuntu/bionic-updates main restricted universe multiverse

从左到又依次为：

镜像网址:http://mirrors.tuna.tsinghua.edu.cn

计算机架构对应关系：

计算机架构	代号
X86	ubuntu
ARM	ubuntu-ports

 

     

系统版本号对应关系:

综上TX2（18.04系统版本）的一条更新格式为

deb http://mirrors.tuna.tsinghua.edu.cn/ubuntu-ports/ bionic-updates main restricted universe multiverse

换源步骤

1.获得root权限

sudo su

2.打开源配置文件

gedit /etc/apt/sources.list

3.删除原来的文件并且换成自己想换的源
