I am not sure if there is an issue with my version, but i am not able to proceed further.

I tried two different versions but still got the same error.

    Hi @ebabade,

    It seems that when the lab guide was converted into PDF a few empty spaces disappeared between "deb" and "https", and between "-L" and "https" respectively. Please try to edit the commands prior to running them in your terminal, to add the missing empty space characters:

    echo "deb https://download...

    curl -L https://download...

    The warnings about apt-key can be disregarded.

    Regards,
    -Chris

    Hi @ebabade,

    For the latest cri-o release, please try the following installation steps, extracted from the cri-o official installation docs https://github.com/cri-o/cri-o/blob/main/install.md#apt-based-operating-systems

    The variables exported below are specific for Ubuntu 20.04 and cri-o version 1.26 (aligned with the latest Kubernetes release). Please keep in mind that the crictl version and installation in Lab exercise 4.6 should also reflect the official crictl installation docs https://github.com/kubernetes-sigs/cri-tools#install

    student@ubuntu:~$ sudo apt update ; sudo apt upgrade -y

    student@ubuntu:~$ sudo -i

    root@ubuntu:~# export OS=xUbuntu_20.04
