The repository 'http://apt.kubernetes.io kubernetes-xenial Release' does not have a Release file
Hi @chrispokorni ,
I am at final stage of my class, I am setting up an HAproxy.
I was installing kubelet,kubeadm,kubectl for the same on a secondary node, but I got an error which isn't letting me install above three services.
Error is at apt-get update followed by unable to locate packages.

yeah same here if you want to get the older version 1.28 in order to practice the upgrade do this:
add this(no newline):
deb [signed-by=/etc/apt/keyrings/kubernetes-apt-keyring.gpg] https://pkgs.k8s.io/core:/stable:/v1.28/deb/ /
to the file: /etc/apt/sources.list.d/kubernetes.listget the key:
curl -fsSL https://pkgs.k8s.io/core:/stable:/v1.28/deb/Release.key | sudo gpg --dearmor -o /etc/apt/keyrings/kubernetes-apt-keyring.gpgconfirm the packages are on your vm:
apt-cache madison kubeadmswitch the 1.28 to 1.29 for the most recent version

Hi @aditya03,
With the change to the new Kubernetes images repo, the installation steps are no longer backward compatible, and we have to be explicit about the desired version for the apt source file and gpg key.
To install components versioned 1.28.1 run the following:
curl -fsSL https://pkgs.k8s.io/core:/stable:/v1.28/deb/Release.key | sudo gpg --dearmor -o /etc/apt/keyrings/kubernetes-apt-keyring.gpg
echo 'deb [signed-by=/etc/apt/keyrings/kubernetes-apt-keyring.gpg] https://pkgs.k8s.io/core:/stable:/v1.28/deb/ /' | sudo tee /etc/apt/sources.list.d/kubernetes.list
sudo apt update
sudo apt install -y kubeadm=1.28.1-1.1 kubelet=1.28.1-1.1 kubectl=1.28.1-1.1
To install components versioned 1.29.1 run the same commands but replace 28 with 29 for gpg key, apt source, and install.

Hi @titu.tiru9,
In the latest lab guide release you can find many installation and configuration steps before getting to this point, that resolve dependencies for the recommended container runtime and the tools needed to successfully download and set the gpg key and apt source for Kubernetes. Try updating your script with those steps as well and let us know if they helped.

Thanks, It worked.

hi, if I want install version 1.21.
any active function to use?0 -
Hi @a957001360h,
Considering that Kubernetes v1.21 is quite outdated, the official installation guide no longer provides installation and configuration instructions for Kubernetes releases older than v1.25.
However, you may try to use the steps presented in my comment above with the necessary corrections for v1.21.
Regards,
-Chris0 -
Thank you Chris!

Hi Rebekah,
I am running WSL2 on Ubuntu - is there a different command for me? Ty0 -
Hi @mattdevops,
Installing Kubernetes in a VM is much better suited for learning purposes as opposed to installing it on WSL. However, if this is the desired approach, the commands depend on your WSL distribution. If it is the default Ubuntu then the commands are the same. For other distributions please consult the official kubernetes.io installation documentation.
Regards,
-Chris

Hi @saks,
Please use the installation and configuration instructions included with the latest course release. You will also find video guides for AWS and GCP infrastructure provisioning, to support the labs.
The instructions referenced above were for an earlier release of the training material.
I am unfamiliar with the CG environment, however, the lab exercises have been completed successfully directly on Google Cloud GCE, AWS EC2, Azure VM, IBM Cloud VS, DigitalOcean VM, and on several local hypervisors, such as VirtualBox, KVM, VMware Workstation and Player.
Regards,
