有没有一种方法可以配置ruby net-ssh使用gpg-agent？我们在整个DevOps部门都使用YubiKeys，并且已经使用Capistrano配置了部署。到目前为止，使用RSA密钥，它们可以正常工作，但是现在它已停止工作，显然使用net-ssh的代理无法读取存储在本地计算机上的yubikey的公共密钥。

这是我得到的错误：

手动SSH连接可以正常工作。

到目前为止，我已经尝试定义环境变量SSH_AUTH_SOCK来指向机器上的GPG代理。

ENV['SSH_AUTH_SOCK'] = "/run/user/1000/gnupg/S.gpg-agent.ssh"

但没有结果...

我找到了一些有关它的信息，但没有任何澄清。 可以配置它吗？
