Hello,
There seems to be a dependency for installing the kubeadm, kubectl and kublet software. The version had been hard coded and now breaks as there is a newer version available. Force an install of the previous version and the install should work. This would be step "6.5" in the lab. apt-get install kubernetes-cni=0.6.0-00 Do this for both the master and worker nodes

    Hello,
    How did you install the nodes you are using? Can you install other packages, are your repos set up? Are these bare metal, AWS, GCE?

    There are a lot of possible issues, but I would look at how you installed your systems, network and repository.

    Regards,

    Hi @whpv,
    It looks like you are missing the init-system-helpers package, required by Kubernetes on Ubuntu 14. You could try using Ubuntu 16 instead and then install Kubernetes.

    thx serewicz & Chris. It is on GCE. I think I have used the wrong Ubuntu version

    I used Ubuntu 18 on GCE and intsallation worked fine for me. DO you recommend downgrading the current 1.14.1 version to 1.13?
    Also I ran this command as per the instruction in Lab 3.1

    apt-get install -y kubeadm=1.14.1-00 kubelet=1.14.1-00 kubectl 1.14.1-00

    Hi @shubhasismathur,
    This discussion started out of a need to address an installation issue with Kubernetes 1.13.1.
    It is not for Kubernetes 1.14.1.
