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

这个也挂了,所以将它也替换成阿里源 - 更新 apt
sudo apt update
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
