给虚拟机的Ubuntu换阿里源

安装的Ubuntu安装东西速度实在是不敢恭维QAQ，因为是国外的网址。
所以我们要换成国内的源，然后就可以尽情飞越了。

首先我们还是要先备份下：sudo cp /etc/apt/sources.list /etc/apt/sources.list.bak
接下来：sudo vim /etc/apt/sources.list
然后把里面的东西全删除，
我们来到https://opsx.alibaba.com/mirror
找到Ubuntu，把里面内容换成如下：

deb http://mirrors.aliyun.com/ubuntu/ bionic main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ bionic main restricted universe multiverse

deb http://mirrors.aliyun.com/ubuntu/ bionic-security main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ bionic-security main restricted universe multiverse

deb http://mirrors.aliyun.com/ubuntu/ bionic-updates main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ bionic-updates main restricted universe multiverse

deb http://mirrors.aliyun.com/ubuntu/ bionic-proposed main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ bionic-proposed main restricted universe multiverse

deb http://mirrors.aliyun.com/ubuntu/ bionic-backports main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ bionic-backports main restricted universe multiverse
