如果Ubuntu Server执行in：
curl https://services.gradle.org/distributions/gradle-7.5.1-bin.zip -O
出现：
% Total % Received % Xferd Average Speed Time Time Time Current
Dload Upload Total Spent Left Speed
0 0 0 0 0 0 0 0 --:--:-- 0:00:19 --:--:-- 0curl: (6) Could not resolve host: services.gradle.org
观察该curl: (6) Could not resolve host: services.gradle.org部分。
如果在in中Fedora Server执行相同的命令，则显示：
% Total % Received % Xferd Average Speed Time Time Time Current
Dload Upload Total Spent Left Speed
0 0 0 0 0 0 0 0 --:--:-- --:--:-- --:--:-- 0
没有错误，但gradle-7.5.1-bin.zip文件是空的。
如果您打开网络浏览器并将其放入https://services.gradle.org/distributions/gradle-7.5.1-bin.zip地址栏中，下载过程将自动开始。
那么如何解决这种情况呢？
笔记以防万一，两个 Linux 都运行为虚拟机在VirtualBox
答案1
显然你的ubuntu服务器中的DNS解析有问题
尝试设置其他 DNS 服务器，例如8.8.8.8或1.1.1.1
查看内容/etc/resolv.conf并设置nameserver 8.8.8.8
更新：
修复 DNS 问题后，添加允许其“遵循重定向”的-L选项curl
这里的问题是 URL 实际上并不提供文件，而是重定向到实际托管该文件的另一个 URL。这是在浏览器中自动完成的，但需要在选项curl中完成。-L
wget请参阅示例的输出：
