Install the AdGuard Ubuntu Appliance for Raspberry Pi

• Insert the microSD card into your computer
• Run the imager and click CHOOSE OS
• Next, choose Use Custom. Select the image you downloaded.
• Select your microSD card and click WRITE.

While it is preparing the disk you can go on to the next step and create your SSH keys for secure access to the appliance.

The 'Secure Shell' protocol provides access to your Ubuntu Appliance and uses cryptographic keys to authenticate you to the device. You need SSH software and keys.

Run the following command:

ssh-keygen -t rsa

1. This starts the key generation process. When you execute this command, the ssh-keygen utility prompts you to indicate where to store the key
2. Press the ENTER key to accept the default location. The ssh-keygen utility prompts you for a passphrase
3. Type in a passphrase

You now have a public and private key that you can use to authenticate.

Your Ubuntu Appliance will be added to your Ubuntu cloud account and use your SSH keys to identify you. Add your keys to your account at https://login.ubuntu.com/ssh-keys.

To do so, run the following command in your terminal.

cat ~/.ssh/id_rsa.pub

Copy the result into the text field on the website. Click import and will have the key set up.

Wait for the Raspberry Pi images to complete. Remove the microSD card from your computer and insert it into the Raspberry Pi. Attach your monitor and keyboard to the Pi, you will use them for the initial device configuration.

If you want to use a wired network, connect your ethernet cable to the Pi before booting.

Power up the Pi by connecting it to your USB power supply.

Your Pi will boot, and present you with a series of configuration choices. You need to ensure that the Pi has internet access so that it can get updates and verify your SSH keys. If you need more help there is a tutorial that goes through these steps in more detail.

Next, you will need to enter your Ubuntu cloud account email address. Your Pi will connect to your cloud account and retrieve your SSH keys.

Your Pi will show an ssh command like:

ssh <Ubuntu SSO user name>@<device IP address>

Your user name is your Ubuntu SSO user name.

Your terminal will welcome you to Ubuntu Core.

Now that you're in your Pi you will be able to use your AdGuard Ubuntu Appliance image.

• Insert the microSD card into your computer
• Run the imager and click CHOOSE OS
• Next, choose Use Custom. Select the image you downloaded.
• Select your microSD card and click WRITE.

Some versions of Windows 10 include an SSH client already, but if yours does not or you're unsure, follow these steps to install one.

1. OpenSSH client is an installable feature of Windows 10.

   To install OpenSSH, start Settings then go to Apps > Apps and Features > Manage Optional Features.

2. Scan this list to see if OpenSSH client is already installed. If not, at the top of the page select Add a feature, then, to install the OpenSSH client, locate OpenSSH Client and click Install

   Once the installation completes, return to Apps > Apps and Features > Manage Optional Features and you should see the OpenSSH component(s) listed.

To install OpenSSH using PowerShell, first launch PowerShell as an Administrator. To make sure that the OpenSSH features are available for install type the command:

Get-WindowsCapability -Online | ? Name -like 'OpenSSH*'

This should return:

Name  : OpenSSH.Client~~~~0.0.1.0
State : NotPresent

Then, install the client features:

Add-WindowsCapability -Online -Name OpenSSH.Client~~~~0.0.1.0

Both commands should return:

Path          :
Online        : True
RestartNeeded : False

After you have installed OpenSSH client you will need to generate user SSH keys to secure the connection to your Raspberry Pi.

Launch 'Windows PowerShell' as an Administrator, and type:

ssh-keygen

Your Ubuntu Appliance will be added to your Ubuntu cloud account and use your SSH keys to identify you. Add your keys to your account at https://login.ubuntu.com/ssh-keys.

To do so, run the following command in your terminal, which will copy your public key to your keyboard.

type ~\.ssh\id_rsa.pub | clip.exe

You can then paste your key result into the text field on your Ubuntu One account. Click import and will have the key set up.

Terminal is the terminal emulator which provides a text-based command-line interface (CLI) to the Unix shell of macOS.

To open the macOS Terminal:

1. In Finder, select Utilities from the Applications folder.
2. Find Terminal in the utilities list.

3. Enter the following command:

   ssh-keygen -t rsa

   This starts the key generation process. When you execute this command, the ssh-keygen utility prompts you to indicate where to store the key

4. Press the ENTER key to accept the default location. The ssh-keygen utility prompts you for a passphrase
5. Type in a passphrase

You now have a public and private key that you can use to authenticate.

Your private key is saved to the id_rsa file in the .ssh directory and is used to verify the public key you use belongs to the same account.

Your Ubuntu Appliance will be added to your Ubuntu cloud account and use your SSH keys to identify you. Add your keys to your account at https://login.ubuntu.com/ssh-keys.

To do so, run the following command in your terminal.
