Lab 4.4: Install CRI-0

rogerh

I'm getting an 'unable to locate package cri-o-1.15' error when trying to install cri-o-1.15 using the command sudo apt install cri-o-1.15. I started searching for an answer and found that there is a problem installing CRI-O in some versions where go 1.13 support is required. I'm using Ubuntu 20.04. But that doesn't explain the fact that the package can't be located. I've tried v1.15, 1.17, and 1.18 with no luck.

Has anyone else seen this problem?

Hi @rogerh,

Did you encounter any issues with prior steps when setting up the repository?

Hi @chrispokorni,

I received some errors with $ sudo apt update:

Hi @rogerh,

Many of the open source projects discussed here are constantly evolving. That impacts many operational steps, from installation to usage. Chances are that the official installation steps have been updated, and they may be found on the CRI-O project's official home page, or on its git repository.

Regards,

I had a similar if not the same problem, also with Ubuntu 20, and went to Openshift docs (https://docs.openshift.com/container-platform/3.11/crio/crio_runtime.html#get-crio-use-crio-engine) to find this:
"CRI-O is not supported as a stand-alone container engine. You must use CRI-O as a container engine for a Kubernetes installation, such as OpenShift Container Platform. To run containers without Kubernetes or OpenShift Container Platform, use podman."

Hi @dwolfe,

This exercise aims to install the CRI-O runtime.

Hi @chrispokorni,
Sorry, all this vocabulary is new to me. It still doesn't look like CRI-O is [supported] under Ubuntu 20 with the Project Atomic Repositories (https://launchpad.net/~projectatomic/+archive/ubuntu/ppa), and sorry if I am not saying this right, but I could not get it to work. Ubuntu 20 is listed on the cri-o website and may work using their install path: (https://cri-o.io/). I just decided to go to an Ubuntu 18 VM and everything seems to work as advertised in the course lab instructions using the project atomic repos.
Best regards,
Don

Hi @dwolfe,

The CRI-O installation steps have not been tested on Ubuntu 20, only on Ubuntu 18.04 LTS, running on the GCE VM instance provisioned following the steps from Lab 1.
For a future course update we will evaluate the later/latest OS release and edit the content where deemed necessary to reflect recommended/supported package management steps.

Regards,
-Chris

Hi Chris,
I am trying on 18.04 LTS, but still getting an error in that the release does not exist:

Hi @cteodor,

The .../k8s/LFS258/SOLUTIONS/... directory from your output suggests you may not be posting in the correct forum. This forum is dedicated to LFS253 - Containers Fundamentals, while the forum dedicated to LFS258 - Kubernetes Fundamentals can be found here.

As far as the error you are reporting, it is due to a typo in your repository URL. Please revisit the steps in Lab 3.1 where the CRI-O repository parameters are set, and ensure the correct parameters and correct URLs are generated.

Regards,
-Chris
