Deploying maas via airship

Hi,
I’m currently deploying airship in a bottle, and it fails every time with the maas installation (if you want the a screen : https://imgur.com/a/uqwWvkZ).

Where can I get informations to understand why it fails? Somewhere under /var/log/ but I didn’t find anything.

Thanks for the help, and I’m here to give you more informations to help.
