如何修复更新错误“Clearsigned 文件无效，出现‘NOSPLIT’（网络是否需要身份验证？）”？

突然sudo apt update在我的 Ubuntu 18.04.6 机器上不再工作了。我收到以下错误：

我的/etc/apt/sources.list：

我的/etc/resolv.conf：

nameserver 192.168.1.1
nameserver 1.1.1.1

我尝试过更改存储库镜像，但没有成功。我尝试sudo apt update在 Ubuntu docker 镜像中运行，但出现了同样的错误。这是否意味着这是网络问题？或者我仍然可以做/检查某些事情？

谢谢！
