你好，我在这 6 次尝试更新我的桌面系统时遇到了一些问题。
抱歉，我不知道是archive.ubuntu.com 服务器临时问题还是我的squid-deb-proxy 包有问题。
观看 /var/log/squid-deb-proxy/access.log 和 apt upgrade 输出我看到：

系统挂起等待数据。这是一个众所周知的问题吗？

我不知道该怎么办。
相关部分似乎与IP有关
151.99.86.73这些请求被拒绝，因为目标 (
151.99.86.73) 未列为允许的域。将此 IP 添加到 /etc/squid-deb-proxy/mirror-dstdomain.acl.d/10-default 应该可以修复它。添加一行包含你就完成了。
在 /etc/squid-deb-proxy/mirror-dstdomain.acl 我已经删除了点“。” 在域前面。
像这样 .archive.ubuntu.com 变成 -> archive.ubuntu.com
第一次测试顺利。
我尝试了一段时间，直到我可以看到错误是否再次出现。
问题解决了，但原因是个谜。
在我的
/etc/squid-deb-proxy/mirror-dstdomain.acl.d/10-default我必须添加一些ip：大部分是必要的，因为一些下载
archive.ubuntu.com解决151.99.86.x/data/<exanumber>/archive.ubuntu.com/ubuntu/...所以当出现新的报错151.99.86.x时，我在acl文件中添加了一个新的ip。
我想了解为什么不使用域地址，除非 151.99.86.x，并且我想了解是否有比在问题出现时添加一个 IP 更好的解决方案。
问候，莱昂纳多
