sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys B53DC80D13EDEF05키 등록하는 명령어 인데 해봤는데 안됨. (구글링했을 때 이 방법이 제일 많았음)
해결방법
curl -s https://packages.cloud.google.com/apt/doc/apt-key.gpg | gpg --dearmor | sudo tee /usr/share/keyrings/kubernetes-archive-keyring.gpg >/dev/null
echo "deb [signed-by=/usr/share/keyrings/kubernetes-archive-keyring.gpg] https://apt.kubernetes.io/ kubernetes-xenial main" | sudo tee /etc/apt/sources.list.d/kubernetes.list
sudo apt update이거 하니까 됨.
