无法安装Google Cloud APT公开签名密钥及Kubernetes APT仓库求助

按照Kubernetes官方文档中Debian发行版的指引，执行以下命令添加Kubernetes仓库密钥：

sudo curl -fsSLo /etc/apt/keyrings/kubernetes-archive-keyring.gpg https://packages.cloud.google.com/apt/doc/apt-key.gpg

执行后返回错误：

curl: (22) The requested URL returned error: 500

直接访问该URL或单独执行curl命令，均返回Google的500内部服务器错误页面，内容如下：

<!DOCTYPE html>

疑问 #

这是Google的服务问题，还是我遗漏了操作步骤？

更新 #

该问题已在GitHub提交相关Issue。

解答 #

这是Google端的服务异常，和你的操作无关，并非遗漏步骤。

临时解决方案可以更换国内镜像源来完成配置：

1. 下载阿里云提供的Kubernetes密钥：

sudo curl -fsSLo /etc/apt/keyrings/kubernetes-archive-keyring.gpg https://mirrors.aliyun.com/kubernetes/apt/doc/apt-key.gpg

2. 添加阿里云的Kubernetes仓库：

echo "deb [signed-by=/etc/apt/keyrings/kubernetes-archive-keyring.gpg] https://mirrors.aliyun.com/kubernetes/apt kubernetes-xenial main" | sudo tee /etc/apt/sources.list.d/kubernetes.list

之后即可正常执行apt update完成仓库同步。
