问题分析

http://cn.archive.ubuntu.com
这个地址应该是挂了，此外尝试挂了梯子仍无法解决，最后决定换个国内源

问题解决

  1. 打开 apt 源的配置文件
sudo vim /etc/apt/sources.list
  1. 将其中 http://cn.archive.ubuntu.com 全部替换成阿里源 http://mirrors.aliyun.com

    实践发现，http://security.ubuntu.com/ubuntu 这个也挂了，所以将它也替换成阿里源
  2. 更新 apt
    sudo apt update
    在这里插入图片描述
    全部命中！解决

额外说明

1. 备份

为了方便还原或者出现其他不可名状的错误，你应该在执行上述步骤前做好备份

cp /etc/apt/sources.list /etc/apt/sources.list.bak

2. 替换命令

sudo sed -i 's/archive.ubuntu.com/mirrors.aliyun.com/g' /etc/apt/sources.list

其他源

中科大：mirrors.aliyun.com
