在 AWS ARM 实例上安装 Puppet Server 7

如何解决在 AWS ARM 实例上安装 Puppet Server 7

在使用 Ubuntu 18.04 (ami-0c925af1500feb25d) 和 20.04 (ami-08b6fc871ad49ff41) 的 AWS Graviton (arm) 实例上安装 Puppet Server 7 期间，我们遇到了 ruby 错误。
Puppet 是根据 official manual 安装的，没有任何额外的配置。顺便说一下，在 amd64 实例上它可以正常工作。在 puppetserver.service 启动期间，我们出现以下错误：
系统日志：

trasporter.sendMail

puppetserver.log：
