I had a similar issue on ubuntu 22.04. It seems that containerd version provided by ubuntu repo is too old for the lasted kubernetes version releases 1 week ago see also: https://kubernetes.io/blog/2022/11/18/upcoming-changes-in-kubernetes-1-26/#cri-api-removal
I solved by manually upgrading the version but maybe sender would suggest a better approach.
Those are the command I used:

sudo su
wget https://github.com/containerd/containerd/releases/download/v1.6.15/containerd-1.6.15-linux-amd64.tar.gz
tar xvf containerd-1.6.15-linux-amd64.tar.gz
systemctl stop containerd
cd bin
cp * /usr/bin/
systemctl start containerd

Thanks for your much appreciated feedback. I have integrated your solution in the setup-container.sh script, while waiting for a container update to be released in the Ubuntu repositories. Please let me know if you have any additional feedback.

Hey @sandervanvugt thanks for coming back, it seems you updated the script but left out CentOS completely there.

[sandervanvugt]

Sorry, I’ll work on CentOS later and provide a full update. The old code was CentOS 7 only anyway, and I’m too busy now to give that an update as well now.
