- An Ubuntu Core image
- A monitor with an HDMI interface
- An HDMI cable
- A USB keyboard
1 Setup an Ubuntu SSO account
2 Download Ubuntu Core
Get the correct Ubuntu Core image for your board:
- Raspberry Pi 2
- Raspberry Pi 3
- Ubuntu Core 16 image for Raspberry Pi 3 (stable) - the older kernel shipped with this image can trigger Wi-Fi issues during first boot, a network cable is recommended.
- Ubuntu Core 16 image for Raspberry Pi 3 (edge) - this image provides reliable Wi-Fi at first boot, but is a daily build and not deemed stable.
- You can verify the integrity of the files using the SHA256SUM and SHA256SUM.gpg files.
3 Flash the microSD card
Copy the Ubuntu Core image on the microSD card by following the installation media instructions.
4 Install Ubuntu Core
- Attach the monitor and keyboard to the board. You can alternatively use a serial cable.
- Insert the microSD card and plug the power adaptor into the board.
5 First boot setup
- The system will boot then become ready to configure.
- The device will display the prompt “Press enter to configure”.
- Press enter then select “Start” to begin configuring your network and an administrator account. Follow the instructions on the screen, you will be asked to configure your network and enter your Ubuntu SSO credentials.
At the end of the process, you will see your credentials to access your Ubuntu Core machine:
This device is registered to <Ubuntu SSO email address>. Remote access was enabled via authentication with the SSO user <Ubuntu SSO user name> Public SSH keys were added to the device for remote access.
Once setup is done, you can login with SSH into Ubuntu Core, from a machine on the same network, using the following command:
ssh <Ubuntu SSO user name>@<device IP address>
Your user name is your Ubuntu SSO user name, it has been reminded to you at the end of the account configuration step.
First boot tips
- During setup,
console-confwill download the SSH key registered with your Store account and configure it so you can log into the device via
ssh <Ubuntu SSO account name>@<device IP address>without a password.
- There is no default
ubuntuuser on these images, but you can run
sudo passwd <account name>to set a password if you need a local console login.
Before you start, get your IoT security story straight
A recent Canonical survey of 2,000 consumers suggests that a shockingly high percentage of connected devices may be vulnerable to botnets, hackers and cyber attacks:
- Only 31% of consumers update the firmware on their connected devices as soon as updates become available.
- 40% of consumers have never performed firmware updates on their connected devices
- 40% of consumers believe that performing firmware updates on their connected devices is the responsibility of either software developers or the device manufacturer
