新安装 - Docker 未安装

支持

在 Ubuntu 21.04 上全新安装。我安装 Discourse 已有数十次，从未遇到问题，但这次却卡住了。

运行 ./discourse-setup 后，我得到以下结果：

为了测试基本网络连接，我使用 traceroute 到 get.docker.com，流量正在离开服务器。

有什么关于可能出现此问题的想法吗？

看起来您已在此服务器上破坏了 IPv6 连接。

是的，我也是这么想的。我将尝试禁用IPV6，强制使用IPV4。

有趣的是，它在IPV4上也无法正常工作。

我无法解释您的问题，但我建议始终使用 LTS 版本（20.04），因为它会持续更长时间。
