我已经使用 juju bootstrap --upgrade tools 选项部署了一个 MAAS 节点，当我运行sudo openstack-install并选择 Autopilot 选项时。它似乎超时了entropy.ubuntu.com。我的代理和 DNS 都已设置好，我可以从 MAAS 服务器执行 wget 和 nslookup，如下所示：

Non-authoritative answer:
24.94.189.91.in-addr.arpa name = okra.canonical.com.
Authoritative answers can be found from:
94.189.91.in-addr.arpa nameserver = ns3.canonical.com.
94.189.91.in-addr.arpa nameserver = ns1.canonical.com.
94.189.91.in-addr.arpa nameserver = ns2.canonical.com.
ns1.canonical.com internet address = 91.189.94.173
ns2.canonical.com internet address = 91.189.95.3
ns3.canonical.com internet address = 91.189.91.139
