Hi,
With the release of a new Kubernetes version, lately, we noticed that prior versions are impacted in one way or another.
Version 1.13.1 used for the labs was impacted by the kubernetes-cni package, where the current dependency is set to kubernetes-cni version 0.7.5 (the lates). Unfortunately, version 0.7.5 is not supported by our lab environment Kubernetes version 1.13.1, thus we need to manually install kubernetes-cni version 0.6.0 which is the supported version by Kubernetes 1.13.1.Before running the installation bash scripts for both Master and Second nodes, please edit the scripts to add an extra step right before the Kubernetes version 1.13.1 components installation step. Once edited, the script should look similar to:
<...> sudo apt-get update sudo apt-get install -y kubernetes-cni=0.6.0-00 sudo apt-get install -y kubeadm=1.13.1-00 kubelet=1.13.1-00 kubectl=1.13.1-00 <...>

Hi @edo.diaz.v
I have set the version of Docker to 18.06.1-0ubuntu1.2~16.04.1 because don't worked with update 18.09...
could you please share how do you explicitly installed the specific docker.io version "18.06.1-0ubuntu1.2~16.04.1"?
I triedsudo apt-get install -y docker.io=18.06.1-0ubuntu1.2~16.04.1
but didn't work out
I tried the instruction on https://docs.docker.com/install/linux/docker-ce/ubuntu/ and I was able to installed that versionsudo apt-get install docker-ce=18.06.1~ce~3-0~ubuntu -y
I'm going to try now if the docker-ce version works as well0 -

Hi @edo.diaz.v
sorry you are right your script works w/ Ubuntu 16.04.6 LTS
my provisioning script created an Ubuntu 18.04.2 LTS that's why it was failing. Apparently on Ubuntu 18 I need to install docker-ce instead@edo.diaz.v said:
What OS do you have?
I have Ubuntu 16.04 and work ok.0 -
Hello,
The fix is to manually install the previous, working copy of the software prior to installing kubectl, kubeadm, and kubelet: apt-get install kubernetes-cni=0.6.0-00 Do this on the master and worker nodes.The particular version of the software was hard-coded into other packages, which have recently updated.
Regards,

On one of my 6 nodes I had to use ----allow-downgrades arg to kubernetes-cni like so:
<...> sudo apt-get update sudo apt-get install -y kubernetes-cni=0.6.0-00 ----allow-downgrades sudo apt-get install -y kubeadm=1.13.1-00 kubelet=1.13.1-00 kubectl=1.13.1-00 <...>
The error I was getting was as follows:
The following packages will be DOWNGRADED: kubernetes-cni 0 upgraded, 0 newly installed, 1 downgraded, 0 to remove and 4 not upgraded. E: Packages were downgraded and -y was used without --allow-downgrades.
Not sure why this happened to just 1 out of 6 nodes.
