ubuntu更改为阿里云镜像

更改为阿里云镜像是为减少安装软件出现问题

• 备份文件：将原本的镜像文件保存一份,

  sudo mv  /etc/apt/sources.list  /etc/apt/sources.list.bak
  
  

• 新建文件：

  sudo vim  /etc/apt/sources.list     
  

• 将阿里云镜像复制到里面去

  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
