因为有 “墙” 的限制, 使用国内的网络访问国外的 “源” 会有诸多限制, 因此在安装 ubuntu 之后往往会更新 “源”.

• 以 ubuntu18.04 更改为 阿里源 为例, 下面简述一下具体的更新步骤:

• 备份原文件 ( 可选, 备份时一个好习惯, 防止改得连母亲都不认识了 )

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

• 修改系统文件 sources.list

  • 方法一 通过命令行的方式修改:

    sudo vi /etc/apt/sources.list
    

  • 方法二 如果采用的是 ubuntu桌面版 也可以使用如下方法:

    sudo gedit /etc/apt/sources.list
    

• 清空文件, 添加如下内容:

  # 阿里源
  deb http://mirrors.aliyun.com/ubuntu/ bionic main restricted universe multiverse
  deb http://mirrors.aliyun.com/ubuntu/ bionic-security main restricted universe     multiverse
  deb http://mirrors.aliyun.com/ubuntu/ bionic-updates main restricted universe     multiverse
  deb 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 main restricted universe     multiverse
  deb-src http://mirrors.aliyun.com/ubuntu/ bionic-security main restricted     universe multiverse
  deb-src http://mirrors.aliyun.com/ubuntu/ bionic-updates main restricted     universe multiverse
  deb-src http://mirrors.aliyun.com/ubuntu/ bionic-proposed main restricted     universe multiverse
  deb-src http://mirrors.aliyun.com/ubuntu/ bionic-backports main restricted     universe multiverse
  

• 输入如下命令进行更新:

  sudo apt-get update
  sudo apt-get upgrade
