You might want to run 'apt --fix-broken install' to correct these.
The following packages have unmet dependencies:

E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or specify a solution).

Hi @aristideboisseau,

What is the Ubuntu release on the GCE instance, and what is the containerd version?

I am attempting to reproduce the issues, on GCE with Ubuntu 24.04 LTS, recommended per the latest release of the lab guide.

Regards,
-Chris

Hi @aristideboisseau,

Without further updates about your environment, I attempted to reproduce your issue. However, following the lab guide instructions, on 2 GCE instances (cp and worker), with Ubuntu 24.04 LTS, I was not able to reproduce the reported issue.

Following the lab guide instructions the containerd.io package installed version 1.7.24 (while the latest at the time of the install was 2.0.1, from github.com/containerd).
Kubernetes v1.30.1 installed the kubernetes-cni package version 1.4.0.
The upgrade in lab 4 went smoothly, without any issues or conflicts.

Regards,
-Chris
