问题：指定K8S节点安装kubeadm kubelet kubectl工具，报错

E: Version '1.20.0-00' for 'kubeadm' was not found
E: Version '1.20.0-00' for 'kubelet' was not found
E: Version '1.20.0-00' for 'kubectl' was not found

 

 解决：

1、重新配置kubenetes仓库为阿里kubenetes仓库

sudo tee /etc/apt/sources.list.d/kubernetes.list <<EOF 

deb https://mirrors.aliyun.com/kubernetes/apt/ kubernetes-xenial main

 

 

2、软件包校验

curl -s https://mirrors.aliyun.com/kubernetes/apt/doc/apt-key.gpg | sudo apt-key add -

 

 3、更新仓库缓存

 

 4、重新安装K8S组件，问题解决
