Lab 2.2. Deploy a New Cluster perfectly followed instructions fail

arqa

I am fairly sure I perfectly followed 01. INTRODUCTION - IMPORTANT: Using GCE to Set Up the Lab Environment as well as Lab 2.1 and Lab 2.2 up to the command "bash k8scp.sh | tee $HOME/cp.out"

I even deleted and created cp again to make sure.

Unfortunately I am not good enough at general linux administration to troubleshoot the particular error without help.

Can somebody help with ideas?

Here is the last part of the output:

Hi @arqa,

You can re-run the script but remove podman and buildah from the installation command, and then install podman manually.

To install podman, as a non-root user execute the following sequence:

sudo apt-mark hold kubeadm kubelet kubectl

. /etc/os-release

echo "deb http://download.opensuse.org/repositories/devel:/kubic:/libcontainers:/stable/xUbuntu_${VERSION_ID}/ /" | sudo tee /etc/apt/sources.list.d/devel:kubic:libcontainers:stable.list

curl -L "https://download.opensuse.org/repositories/devel:/kubic:/libcontainers:/stable/xUbuntu_${VERSION_ID}/Release.key" | sudo apt-key add -

sudo apt update

sudo apt upgrade -y

sudo apt install -y gnupg2

sudo apt install -y podman

sudo apt install -y podman --fix-missing

If the installation errors persist, re-run the following sequence:

sudo apt install -y gnupg2

sudo apt install -y podman

sudo apt install -y podman --fix-missing

sudo apt install -y gnupg2

sudo apt install -y podman --fix-missing

Hello Chris,

thank you for your support. Unfortunately, on the existing node this did not help. Fortunately, when I tried creating a new node and following the instructions closely a third time - this time it worked fine.

Regards,
David
