我现在使用的是 Ubuntu 16.10，我需要将其更新为仍受支持的版本。因此我尝试遵循以下指南： https://www.linuxbabe.com/ubuntu/upgrade-ubuntu-16-10-to-17-04但是运行从 16.10 更新部分中的命令不起作用。它们给出有关存储库未更新的错误。有人能告诉我更新到受支持版本的方法吗？我不太在乎哪一个，只是 16.10 不再受支持。
以下是运行 sudo apt update && sudo apt dist-upgrade 时收到的错误消息

下一个命令运行正常，没有任何错误。我不得不弄乱一些链接，否则它不会让我发布它。

再也没有简单、经过测试、受支持的方法来做你想做的事情了。那扇窗户已经关闭了。现在对你来说，唯一简单且受支持的方法是备份你的数据，然后安装受支持的 Ubuntu 版本。
有多种方法可以实现您的目标，但这些方法并不容易，也不太快捷。仅推荐熟练的 apt 用户使用，因为它们涉及编辑文本文件、使用终端，有时还涉及解决版本冲突。
非 LTS Ubuntu 版本每六个月发布一次，支持期为九个月。除非你更改设置，否则你的系统可能会在三个月内每天都提醒你从 16.10 升级到 17.04，而这个窗口期是开放的。
如果您不想每六个月就陷入这种困境，那么 Ubuntu 的 LTS 版本每两年发布一次（14.04、16.04，即将推出 18.04），并提供五年的支持。
