however , I just paste the full preseed into ubuntu.seed in cubic , but it didn't "full automate" install ubuntu.

I see the language and keyboard were defaulat in BR language. that means the preseed did work in some way, but what I really want to is "auto" select language/keyboard , configure user account , install some packages without human ( so called "unattended install " )

and BTW , I use ubuntu jammy desktop as based ISO in cubic , what's your choice ?
