Ubuntu存储库没有Release文件
这类似于Xenial存储库没有Release文件 ，但那里的修复程序对我不起作用。
在几天的Ubuntu 16.04安装上运行sudo apt-get update时，它会返回以下错误消息：

我已经尝试了sudo rm /var/lib/apt/lists/*和我的/etc/apt/sources/list已经注释了第52行，并且第54行不存在。 （我在这个和其他论坛上发现的两种解决方案）。
你的/etc/apt/sources.list底部的第三行似乎是错误的：
deb http://archive.ubuntu.com xenial universe
我认为该行是造成错误的原因，所以我建议您删除它。
编辑：
执行此操作后，可能需要清理程序包缓存，您可以通过运行以下命令来执行此操作：
sudo rm /var/lib/apt/lists/*
然后：
sudo apt update
就我而言，这个问题真的很愚蠢。 我的服务器外没有网络访问权限。 我花了很长时间才意识到这是我的问题;-)
