Raspberry Pi 2 Model B
For the basic procedure, I referred to the following site. https://ubuntu.com/download/raspberry-pi-core
Why create an account? At the time of the first startup setup, access the account created here and do something like activation. Also, the user name set in the account will be the Ubuntu Core user name. It seems to be created because of the mechanism.
Import the SSH key ...
ssh-keygen
Will create id_rsa and id_rsa.pub in the specified folder. Details were written here. How to use the ssh-keygen command Paste the contents of id_rsa.pub to the SSH key on the account page and register.
I used "ubuntu-core-18-armhf + raspi.img.xz".
Press Enter to proceed. Set up the network. Enter the email address of your Ubuntu one account.
ssh <Ubuntu SSO user name>@<device IP address>
You can log in by typing the above information displayed on the screen.
I've only noticed this far, but Ubuntu Core doesn't even have a command line. .. .. To be honest, I was surprised because I expected that only the command line would appear when I started it up, like an old computer that was super lightweight. I'm going to touch on what I can do with this.
