Lab 2.2 - Failing to work
I have run through the aws setup.
I went through the setup steps depicted here.
Configured everything appropriately, including running swapoff -a
; however, after I ssh into my instance and attempt to run the lab with this command bash k8scp.sh | tee $HOME/cp.out
, I get the following output:
The following information may help to resolve the situation: The following packages have unmet dependencies: buildah : Depends: crun (>= 100:0.18-3) but it is not going to be installed cri-o-runc : Depends: libc6 (>= 2.28) but 2.27-3ubuntu1.5 is to be installed podman : Depends: crun (>= 100:0.19.1-1) but it is not going to be installed Recommends: containernetworking-plugins (>= 100:1.0.0-1) but it is not going to be installed Recommends: fuse-overlayfs but it is not going to be installed E: Unable to correct problems, you have held broken packages. sed: can't read /etc/containers/storage.conf: No such file or directory Failed to enable unit: Unit file crio.service does not exist. Failed to start crio.service: Unit crio.service not found. Warning: apt-key output should not be parsed (stdout is not a terminal)
I'm running t2.large
in AWS with 2 CPU
, 8 GB RAM
.
I'm able to SSH into my AWS instance.
I'm able to curl the project files in my AWS instance.
I'm not able to run bash k8scp.sh | tee $HOME/cp.out
.
I have spent many hours attempting to run this lab in a variety of environments (virtual box, now AWS), all with the same result. I am absolutely spinning my wheels, any help would be appreciated..

Do you use the Ubuntu Focal image? Your output kinda suggests that the base system is not the right version.
I installed it a few days ago. (After figuring out the quirk with the course material URL, it worked fine.)
I used this Vagrant file:
Vagrant.configure("2") do |config| config.vm.provider "virtualbox" do |provider| provider.gui = false provider.memory = 8192 end config.vm.network "public_network" config.vm.box = "ubuntu/focal64" config.vm.define "vm1" do |node| node.vm.hostname = "vm1" node.vm.network :private_network, ip: "10.110.0.100" end config.vm.define "vm2" do |node| node.vm.hostname = "vm2" node.vm.network :private_network, ip: "10.110.0.200" end config.vm.provision "shell", inline: <<-EOF set -ex sudo apt-get update sudo apt-get install policycoreutils selinux-utils selinux-basics -y sudo setenforce 0 || : sudo swapoff -a || : EOF end
After the
vagrant up
, I
1. usedvagrant ssh-config
to get the ssh connection config
2. stopped the machines
3. disabledAdapter 1
in the machine settings for both vm1 and vm2
4. then started the machines manually.Step 3 is necessary as otherwise the TLS certificate of the api-server will be invalid (Not contain the IP you need). Alternatively, you may try to modify the
k8scp.sh
script but I didn't have to do that this way.Following this, you should be able to follow the tutorial to install the cluster.

Hi @dillonjcooper2,
Would you be able to confirm that the EC2 instances are running Ubuntu 20.04 LTS?
