You should try to update PGP keys from the keyserver provided by Canonical:
sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv-keys 6A030B21BA07F4FB
Executing: /tmp/apt-key-gpghome.F7OvCVWiqu/gpg.1.sh --keyserver hkp://keyserver.ubuntu.com:80 --recv-keys 6A030B21BA07F4FB
gpg: key 6A030B21BA07F4FB: public key "Google Cloud Packages Automatic Signing Key <[email protected]>" imported
gpg: Total number processed: 1
gpg: imported: 1
next:
sudo apt update && sudo apt upgrade
will do the rest of the job.
If problem still exists, binaries also can be downloaded directly:
wget https://storage.googleapis.com/kubernetes-release/release/v1.10.1/bin/linux/amd64/kubeadm
wget https://storage.googleapis.com/kubernetes-release/release/v1.10.1/bin/linux/amd64/kubectl
wget https://storage.googleapis.com/kubernetes-release/release/v1.10.1/bin/linux/amd64/kubelet

I am suffering below problem.
I use ubuntu 16.04. I am following guide document, but it does not works for me.
# cat /etc/apt/sources.list.d/kubernetes.list deb http://apt.kubernetes.io/ kubernetes-xenial main # curl -s https://packages.cloud.google.com/apt/doc/apt-key.gpg | apt-key add - OK # apt-get update Hit:1 http://kr.archive.ubuntu.com/ubuntu xenial InRelease Hit:2 http://kr.archive.ubuntu.com/ubuntu xenial-updates InRelease Hit:3 http://kr.archive.ubuntu.com/ubuntu xenial-backports InRelease Hit:4 http://security.ubuntu.com/ubuntu xenial-security InRelease Get:5 https://packages.cloud.google.com/apt kubernetes-xenial InRelease [8993 B] Ign:5 https://packages.cloud.google.com/apt kubernetes-xenial InRelease Fetched 8993 B in 1s (5258 B/s) Reading package lists... Done W: GPG error: https://packages.cloud.google.com/apt kubernetes-xenial InRelease: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 6A030B21BA07F4FB W: The repository 'http://apt.kubernetes.io kubernetes-xenial InRelease' is not signed. N: Data from such a repository can't be authenticated and is therefore potentially dangerous to use. N: See apt-secure(8) manpage for repository creation and user configuration details.
I want to upgrade kubeadm version. How to fix this?
