APT repository contains 1.5.2 instead of 1.5.4/1.5.5

[marccarre]

What happened:

When installing Kubernetes packaging using apt as per these intructions, one gets versions 1.5.2 at the moment (see here) under Ubuntu Xenial:

[...]
Package: kubectl
Version: 1.5.2-00
[...]
Package: kubelet
Version: 1.5.2-00
[...]

What you expected to happen:

Either get 1.5.4 as it was happening last week/the week before; or get 1.5.5 given it has been released since then and is returned by:

$ curl https://storage.googleapis.com/kubernetes-release/release/stable.txt
v1.5.5

I certainly did not expect a rollback to 1.5.2.

How to reproduce it:

Under a machine with Ubuntu Xenial:

# apt-get update && apt-get install -y apt-transport-https
# curl -s https://packages.cloud.google.com/apt/doc/apt-key.gpg | apt-key add -
# cat <<EOF > /etc/apt/sources.list.d/kubernetes.list
deb http://apt.kubernetes.io/ kubernetes-xenial main
EOF
# apt-get update
# apt-get install -y kubelet kubeadm kubectl kubernetes-cni
[...]
Setting up kubelet (1.5.2-00) ...
Setting up kubectl (1.5.2-00) ...
[...]
# kubelet --version
Kubernetes v1.5.2
# kubectl version --short
Client Version: v1.5.2
[...]

Anything else we need to know:

Relates to:

• keep apt.kubernetes.io up to date #162
• apt.kubernetes.io should keep old versions #234
