由于 17.04 不再受支持，我决定升级到 17.10，但遇到以下无法解决的错误：
Err http://archive.ubuntu.com/ubuntu stable Release
404 Not Found [IP: 91.189.88.161 80]

有人可以帮忙解决吗？

首先我们将修复您的存储库：
sudo sed -i -re 's/([a-z]{2}\.)?archive.ubuntu.com|security.ubuntu.com/old-releases.ubuntu.com/g' /etc/apt/sources.list
这应该会调整你的 /etc/apt/sources.list 以使其看起来类似于此：
德布http://old-releases.ubuntu.com/ubuntu/zesty-updates 主页
德布http://old-releases.ubuntu.com/ubuntu/zesty-backports 主要
德布http://old-releases.ubuntu.com/ubuntuzesty-security 主页
德布http://old-releases.ubuntu.com/ubuntu热情主宇宙受限多元宇宙
然后运行：
sudo apt-get update && sudo apt-get dist-upgrade
最后运行：
sudo do-release-upgrade
