pk-client-error-quark 和 apt-get 更新错误

如果我尝试更改“软件和更新”应用程序下载更新的服务器，我会收到以下错误：

pk-client-error-quark
E: archive.canonical.com/ubuntu focal
InRelease is not (yet) available (impossible connecting to archive.canonical.com:443 (91.189.91.15) - connection refused

还sudo apt-get update返回一些错误：

$ sudo apt-get update

Err:1 https://archive.canonical.com/ubuntu focal InRelease

这是怎么回事？我去过好几个国家，这可能把存储库搞乱了。

附加信息：

$ lsb_release -a
No LSB modules are available.

显然，问题（或至少部分问题）在于页面上列出的一些官方支持的镜像Ubuntu 存档镜像确实没有Focal Fossa版本发布。

我编辑了/etc/apt/sources.list列表，只列出了那些确定有发行版的镜像（在我亲自检查之后），然后我sudo apt update --fix-missing && sudo apt upgrade。我想我还需要添加其他（更新的）镜像，但现在错误已经消失了：

$ sudo apt update --fix-missing && sudo apt upgrade
