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），它支持通过 SSH 运行“cos-extensions install gpu”来安装简单的 GPU 驱动程序（参见Google 文档）。

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，您可以在此处找到它的报告以及在此处找到带有解决方法的类似线程。 新 COS 版本的发布和更新驱动程序的发布之间似乎存在延迟。

不过我cos-extensions list刚才跑了，好像有驱动可用：

$ cos-extensions list
Available extensions for COS version 89-16108.403.47:

[gpu]
450.119.04 [default]
450.80.02

还有签名：
