gpu - cos-extensions 安装 gpu 无法在 GCP Compute Engine VM 上下载驱动程序签名

Question

我正在 GCP Compute Engine 上使用支持 GPU 的 VM。
作为操作系统，我使用容器优化版本 (COS 89-16108.403.47 LTS)，它通过 SSH 运行“cos-extensions install gpu”来支持简单的 GPU 驱动程序安装(参见 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。
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!

Answer 1

这似乎是一个已知问题，您可以找到它报告的 here和类似的解决方法线程 here .
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
