I successfully installed the Ubuntu Core in a Raspberry Pi 3. The system starts, I completed setup and now when I start the system, states firstly "No ethernet found", load all libraries and it goes straight to a screen like this:

Ubuntu Core 16 on IP

Host key fingerprints
ED25519 SHA256: ABCD

To login: ssh my_user@

Obviously I am not being able to ssh into the device, I get the error: "ssh: connect to host port 22: Connection timed out". So, I'd like to get help on two issues:

  1. How do I enter Ubuntu Core Setup again to fix ethernet ?
  2. How do I access the Ubuntu Core command line?

    The error message ssh: connect to host port 22: Connection timed out says you don't have sshd running on the device. – waltinator Jun 22 '18 at 19:31
  • I understand, but I am not being able to access command line to start the sshd service. It's a fresh installation. – Rubens_Zimbres Jun 22 '18 at 19:35

Sorry about my previous ignorance. I solved both issues. To answer question 1 I flashed the image again with Etcher in Raspberry Pi after formatting the SD Card. Then I SSH'd into Ubuntu Core with proper id_rsa key, passphrase and password.

Here is a guide I developed after succeeding:
