Hello,
We use Balena in an enterprise environment.
After successful deployment of our new release I have been tasked to create a preload Balena image with our latest release.
But I have attempted multiple times on fresh Ubuntu virtual machines and always get same error. This is with then latest Balena CLI, Ubuntu 24.04 and Docker

While using the --debug options I get more information, but it is not very informative.
Maybe someone can get me on track what is wrong here ?
