Can you include the yafti.yaml you're using? We have not yet migrated to pydantic version v2 but I know there are those interested in doing so.

Also, can you run pip freeze on your environment? This error looks like it's coming from a mismatched version of pydantic dependency installed.

Sure! It's just the file provided as stock with the image I was using: https://github.com/secureblue/secureblue/blob/live/config/files/usr/share/ublue-os/firstboot/yafti.yml

Also, can you run pip freeze on your environment? This error looks like it's coming from a mismatched version of pydantic dependency installed.

Agreed on the pydantic version probably being mismatched. I'll run a pip freeze when I get a chance in a bit.

@alexispurslane I'll working on removing or updating this in the near future.
