问题描述
我正在 GCP Compute Engine 上使用支持 GPU 的虚拟机。
作为操作系统，我使用容器优化版本 (COS 89-16108.403.47 LTS)，该版本通过 SSH 运行“cos-extensions install gpu”来支持简单的 GPU 驱动程序安装（请参阅 Google doc）。
到目前为止，这一直运行良好，直到几天前我开始收到一条错误消息，说某些驱动程序签名的下载失败（请参阅下面的完整错误消息），从那以后我无法让它工作。
非常感谢！

解决方法
这似乎是一个已知问题，您可以发现它报告了 here 和类似的线程，并提供了解决方法 here。
新的 COS 版本发布和更新驱动程序的发布之间似乎存在延迟。
但是，我刚刚运行了 cos-extensions list，似乎有可用的驱动程序：
$ cos-extensions list
Available extensions for COS version 89-16108.403.47:
[gpu]
450.119.04 [default]
450.80.02
