Lab 4.5 Install cri-o and cri-o-runc

nicocerquera

Following the last portion of the section, I am not able to successfully install cri=o-runc

---

sudo apt install cri-o-runc

Reading package lists... Done
Building dependency tree
Reading state information... Done
Package cri-o-runc is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source

E: Package 'cri-o-runc' has no installation candidate

Does anyone know why is that the case?

We use cri-o-runc in the next section so I am stuck in here

Hi @nicocerquera,

The installation step apt install runs successfully if the prior steps completed successfully as well. What method did you use to provision your VM (local hypervisor or cloud)? What OS are you running? Can you provide the history of prior commands, so we can validate that they were entered correctly at the CLI?

Regards,

Hey Chris, this is the version, will post here again the command history, for some reason I thought I had sent them already.

This last package is removed from the repo, maybe is compiled with the main package cri-o, you can complete the labs without it, and if need runc, it will recommend or suggest to install runc

nicocerquera

yeah, I do have runc installed:
runc --version
runc version 1.0.2
commit: v1.0.2-0-g52b36a2
spec: 1.0.2-dev
go: go1.16.10
libseccomp: 2.5.1

@chrispokorni Sorry but I do not understand this question ( beginner here ) "What method did you use to provision your VM (local hypervisor or cloud)?" could you expand on this please.

With regards to the history:

Also, will not having cri-o-runc be an issue as we continue with other exercises on this class?

Hi @nicocerquera,

It seems you may be running a dated OS release for this course. The latest/current course update release is based on another guest OS release. Please revisit Chapter 1 for recommended VM provisioning methods and the guest OS to be installed on the VM.

Regards,
-Chris

hi @chrispokorni,

I have updated the OS accordingly:

However, I am still not able to install cri-o-runc

Hi @nicocerquera,

I would invite you to revisit the installation steps from the lab guide and ensure that there are no typos in the commands entered/pasted at the CLI. The accuracy of these commands is critical for a successful installation of the desired software packages.
