ubuntu - sudo apt-get 更新连接超时
问题描述
在 Ubuntu 20.04.3 LTS (GNU/Linux 5.4.0-89-generic x86_64) - 数据中心的虚拟机上，我尝试使用 apt-get update 在我的服务器上安装新软件包，但无法使用它。
我有这个错误：
Err:1 http://archive.canonical.com/ubuntu focal InRelease

我的存储库如下：

我停用了 IPv6，因为我遇到了一个错误：101 网络无法访问。为此，我修改 /etc/sysctl.conf 并添加以下行：
net.ipv6.conf.all.disable_ipv6 = 1
net.ipv6.conf.default.disable_ipv6 = 1
net.ipv6.conf.lo.disable_ipv6 = 1
当我 ping google 时，我得到了响应（我想我不使用代理，因为 172.217.31.78 是公共地址）：
64 bytes from kul08s07-in-f14.1e100.net (172.217.31.78): icmp_seq=1 ttl=115 time=60.1 ms
--- google.com ping statistics ---
8 packets transmitted, 8 received, 0% packet loss, time 7010ms
如果我 ping la.archive.ubuntu.com:80 (91.189.91.38) 也是一样，我发送的所有包都已收到。
为什么我无法连接到 ubuntu 存储库？我注意到我的 80 端口已关闭，这是原因吗？
