• W: 部分索引文件下載失敗。如果忽略它們，那將轉而使用舊的索引文件。
• 這是因為cn.archive.ubuntu.com被牆了，無法連接,
• 需要切換到國內源.
• 首先備份源列表:
• sudo cp /etc/apt/sources.list /etc/apt/sources.list_backup
• 而后用gedit或其他編輯器打開:
• sudo gedit /etc/apt/sources.list
• #添加阿里源
  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-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

• 最后執行如下命令更新源
  ##更新
  sudo apt-get update
  sudo apt-get upgrade

  另外其他幾個國內源如下：

• 將cn.archive.ubuntu.com替換為阿里源mirrors.aliyun.com
• 然后，刷新列表:
• sudo apt-get update
• 幾個國內源
• //阿里源http://mirrors.aliyun.com
• //中科大源http://mirrors.ustc.edu.cn
• //163源http://mirrors.163.com
• //清華源http://mirrors.tuna.tsinghua.edu.cn
