最终排查到的原因：本机器的cpu是arm架构，各种教程基本默认教你配x86的源，用错源自然找不到所需的包裹信息，报404错误。

解决方法：把阿里源or清华源的url里的ubuntu全部替换成ubuntu-ports，然后重新apt-get update，比如Ubuntu 22.04的清华源改成如下：

deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu-ports/ jammy main restricted universe multiverse
deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu-ports/ jammy-updates main restricted universe multiverse
deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu-ports/ jammy-backports main restricted universe multiverse
deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu-ports/ jammy-security main restricted universe multiverse
