我正在尝试使用 Openstack 设置云。由于官方 MAAS Ubuntu Cloud 文档步骤非常简短，我断断续续花了将近一个月的时间才完成安装。由于我经历了所有的反复试验，我肯定尝试了 50 次删除、重新添加和重新调试节点……
无论如何，我终于在今天晚上部署了我的第一个节点！我委托了一个测试节点并运行sudo openstack-install以启动安装过程。它运行了大约 15-20 分钟，节点现在处于“已部署”状态，但安装再次失败。这是我从 MAAS 错误日志中得到的错误：

是不是下载操作失败了？我尝试在 MAAS 设置中禁用代理设置（按照已解决的回复这个 github 问题) 但我现在没有什么主意了，感觉自己在重复做同样的事情。
编辑：我刚刚意识到我不能从节点 ping 外部网络，但我能nslookup 一个 IP，所以 DNS 有点工作正常。我认为这一定是网络问题？我会继续测试，如果有任何进展，我会报告。
任何帮助都将不胜感激。谢谢。
