我在 WSL2 上运行 Ubuntu 22.04 LTS，遇到了某种 apt 问题，在网络连接正常且 nslookups 确认的情况下，我总是生成幻影Error: Timeout Was Reached。我说幻影是因为我检查了所有可能的日志，但找不到任何提示相关错误或连接错误的内容。我检查过的日志，
- 日志控制
- apt 术语和历史记录
- 系统日志
- 消息
我也尝试了每个 apt clean、remove、autoremove 命令。
我尝试以更详细的模式运行更新，但仍然没有指示为什么apt update尽管能够找到其他请求的包，但总是以超时结束。我尝试使用 22.04 的 vanilla sources.list 编辑 sources.list，但仍然超时。我尝试一次启用一个源，但无论提取是否成功，它们最终都会超时。
我完全不知道是什么原因造成的，如果有更多日志可以分享，请告诉我。
以下是 输出的一个示例sudo apt update：

如果没有证据，如果我不得不猜测，我会说这一切都始于几周前一次拙劣的 mysql 卸载，不确定这是否提供了任何有用的信息。
