kubernetes: kubelet dependency to kubernetes-cni failure

I think this issue should reopen because of last night update Fri, 05 Oct 2018 23:13:00 UTC you can see the update date link below; https://packages.cloud.google.com/apt/dists/kubernetes-xenial/main/binary-amd64/Release

New version of kubernetes-cni debian package repo has been updated/added but kubeadm and kubectl are not. That’s why it doesn’t work because apt-get wants to install the latest version. That’s why it doesn’t work. If someone remove 0.6.0-02 version from release list I think installation will work

here is packages list; https://packages.cloud.google.com/apt/dists/kubernetes-xenial/main/binary-amd64/Packages

$ apt-get update && apt-get install -y kubeadm kubelet kubectl

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created

The following information may help to resolve the situation:

The following packages have unmet dependencies:
 kubeadm : Depends: kubernetes-cni (= 0.6.0) but 0.6.0-02 is to be installed
 kubelet : Depends: kubernetes-cni (= 0.6.0) but 0.6.0-02 is to be installed
E: Unable to correct problems, you have held broken packages.

Temporary workaround:

apt-get install kubernetes-cni=0.6.0-00

Please re-open this, its still an issue:

$ sudo apt-get update && sudo apt-get install --reinstall -y kubelet kubeadm
...
The following packages have unmet dependencies:
 kubeadm : Depends: kubernetes-cni (= 0.6.0) but 0.6.0-02 is to be installed
 kubelet : Depends: kubernetes-cni (= 0.6.0) but 0.6.0-02 is to be installed

It is happening because, kubernetes-cni lates version is 0.6.0-02 which is incompatible with kubeadm and kubelet. it can be solved by installing specific version of kubernetes-cni that is 0.6.0-00. Command: apt-get install kubernetes-cni=0.6.0-00

Solution found here: http://jee-appy.blogspot.com/2018/10/kubelet-depends-kubernetes-cni-060-but.html

Still happening on ubuntu xenial:

root@master:~# apt-get update && apt-get install -y --allow-unauthenticated kubeadm kubelet kubectl

This issue is affecting me too. The fix mentioned in this comment above is working.

This bug was fixed long time ago.
