Installation instructions
What you'll need
- A microSD card (4GB minimum, 8GB recommended)
- A Raspberry Pi 3 or 4
- A computer with a microSD card drive
- A micro-USB power cable (USB-C cable for the Pi 4)
- A monitor with an HDMI interface
- AHDMI cable for the Pi 3 and a MicroHDMI cable for the Pi 4
- A USB keyboard
These steps will flash your Nextcloud Ubuntu Appliance to your Raspberry Pi with a Ubuntu machine, and get you logged in.
-
Install the Raspberry Pi Imaging Tool
-
Prepare the microSD card
Warning- 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

.
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.
-
Generate Secure Shell (SSH) keys
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
- This starts the key generation process. When you execute this command, the ssh-keygen utility prompts you to indicate where to store the key
-
Press the
ENTER
key to accept the default location. The ssh-keygen utility prompts you for a passphrase - Type in a passphrase
You now have a public and private key that you can use to authenticate.
-
Create an Ubuntu SSO 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.
cat ~/.ssh/id_rsa.pub
Copy the result into the text field on the website. Click
import
and will have the key set up. -
Boot your Raspberry Pi from the microSD card
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.
-
SSH in
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.
-
That's it
Now that you're in your Pi you will be able to use your Nextcloud Ubuntu Appliance image.
What you'll need
- A microSD card (4GB minimum, 8GB recommended)
- A Raspberry Pi 3 or 4
- A computer with a microSD card drive
- A micro-USB power cable (USB-C cable for the Pi 4)
- A monitor with an HDMI interface
- AHDMI cable for the Pi 3 and a MicroHDMI cable for the Pi 4
- A USB keyboard
These steps will flash your Nextcloud Ubuntu Appliance to your Raspberry Pi with a Windows machine, and get you logged in.

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.
-
Install OpenSSH
The 'Secure Shell' protocol provides access to your Ubuntu Appliance and uses cryptographic keys to authenticate you to the device. You will need SSH software and keys.
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.
-
OpenSSH client is an installable feature of Windows 10.
To install OpenSSH, start Settings then go to
Apps > Apps and Features > Manage Optional Features
. -
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, locateOpenSSH Client
and clickInstall
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
-
-
Generate Secure Shell (SSH) keys
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
-
Create an Ubuntu SSO 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, 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. -

Generate Secure Shell (SSH) keys
The 'Secure Shell' protocol provides access to your Ubuntu Appliance and uses cryptographic keys to authenticate you to the device. You will need SSH software and keys.
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:
-
In Finder, select
Utilities
from the Applications folder. -
Find
Terminal
in the utilities list. -
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
-
Press the
ENTER
key to accept the default location. The ssh-keygen utility prompts you for a passphrase - 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.

Start using your Nextcloud Ubuntu Appliance
When you start Nextcloud for the first time you make an account and go through some initial configuration. To do so, open a browser and go to:
On Raspberry Pis and PCs:
On a Virtual machine:
http://<IP-of-your-appliance>
After that, you can start using your new Nextcloud server. For more information and documentation visit the Nextcloud website.
