如何更改源

1/ 在修改source.list前，最好先备份一份

执行备份命令

sudo cp /etc/apt/sources.list /etc/apt/sources.list.old

2/ 执行命令打开source.list文件：

可以用vim，gedit,atom等工具打开

sudo vim /etc/apt/source.list

或

sudo gedit /etc/apt/source.list

或(你得自己安装atom，我觉得挺好的一个工具)

sudo atom /etc/apt/source.list

3/复制源

把下面的任意一下复制到source.list中去，并覆盖原来的文件内容。
