作为我的 Vagrantfile 的一部分，我有

config.vm.box = "hashicorp/bionic64"
  config.vm.provision "shell", path: "https://get.docker.com", name: "dockers"

我使用公司代理。我将公司证书附加到 C:\HashiCorp\Vagrant\embedded\cacert.pem 。此外，我将此环境变量 CURL_CA_BUNDLE 和 SSL_CERT_FILE 都设置为包含证书的 C:\HashiCorp\Vagrant\embedded\cacert.pem 。

但 vagrant up 仍然失败，并显示以下消息：

schannel: next InitializeSecurityContext failed: Unknown error (0x80092012) - The revocation function was unable to check revocation for the certificate.
 INFO interface: Machine: error-exit ["Vagrant::Errors::DownloaderError", "An error occurred while downloading the remote file. The error\nmessage, if any, is reproduced below. Please fix this error and try\nagain.\n\nschannel: next InitializeSecurityContext failed: Unknown error (0x80092012) - The revocation function was unable to check revocation for the certificate.\r"]

我猜是 Ruby（由 Vagrant 使用）找不到证书或获取撤销列表的调用被阻止。您知道这里的具体问题是什么以及如何修复它吗？

更新

在调试模式下，curl（可能是从 Ruby 调用？）似乎正在尝试下载文件
