我正在 GCP 计算引擎上使用支持 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），它支持通过 SSH 运行“cos-extensions install gpu”来安装简单的 GPU 驱动程序（请参阅谷歌文档 https://cloud.google.com/container-optimized-os/docs/how-to/run-gpus).
到目前为止，这一直工作得很好，直到几天前我开始收到一条错误消息，指出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），从那以后我就无法让它工作。
有人可以确认我在这里遇到错误或帮助我解决此问题吗？
提前谢谢了！

这似乎是一个已知问题，您可以找到已报告的问题here https://issuetracker.google.com/issues/191302490以及具有解决方法的类似线程here https://issuetracker.google.com/issues/164134488.
看起来新 COS 版本的发布和更新驱动程序的发布之间存在延迟。
然而，我跑了cos-extensions list刚才，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
