2、解决方案

step 1

sudo curl -fsSLo /usr/share/keyrings/ /apt/doc/

手动下载/apt/doc/
将下载后的复制到/usr/share/keyrings/文件下

sudo cp  /usr/share/keyrings/

step 2

echo "deb [signed-by=/usr/share/keyrings/] / kubernetes-xenial main" | sudo tee /etc/apt//

调整为

echo "deb [signed-by=/usr/share/keyrings/] /kubernetes/apt kubernetes-xenial main" | sudo tee /etc/apt//
