更新:这不再是必要的，因为 Authorize.net 已更新其生产服务器的证书.

您可能会发现它突然停止工作，因为 Ubuntu ca-certificates 软件包在最近的更新中放弃了对它们的支持:

You may have found this to stop working all of a sudden because the Ubuntu ca-certificates package just dropped support for them in the most recent update:

前几天我和我的同事在一个客户身上遇到了这个问题——他们的捐款突然停止了.

My coworkers and I encountered this with a client just the other day--their donations suddenly stopped working.

真正的解决方案是 Authorize.net 需要更新他们的证书.但是，与此同时，您可以只添加一个缺少的证书.我在此处汇总了有关如何在 Ubuntu 中执行此操作的说明:

The real solution is that Authorize.net needs to update their certificate. However, in the meantime, you can just add the one missing certificate. I put together notes on how to do this in Ubuntu here:

我还在 https 上保存了一个根证书(尽管它可能不安全)://github.com/agh1/ca-certificate-for-authorize.net

同样，我希望这只是一个短期解决方案，直到他们获得新证书，但这将是一个很好的权宜之计.

Again, my hope is that this only needs to be a short-term solution until they get a new certificate, but this will be a good stop-gap.
