You can always download the latest NeonOS image from neon.ai. In most cases though, you can perform in-place updates from your device. Updates will generally take about 30 minutes to complete and once started, you will not be able to use your device until updates finish.
Updates via Skill Intent (since Neon Core 22.10.2a15)
For images as of December 20, 2022, you may check for updates by asking your
"are there any updates?". Neon will tell you the installed Neon Core version
and if there is an update available. If a newer version is available, you will be
given the option to install it.
Manual Update for Installations (prior to Neon Core 22.10.2a15)
If you have an older version of Neon that does not include the update skill, you may still update your device manually without having to install a new image.
Update via SSH
If you have another computer available on the same network as your Neon device,
you can connect via SSH to start the update.
1. Ask your Neon device
"what is your IP address" and type it somewhere you can copy & paste from.
2. From a terminal on your other computer, enter
ssh neon@<device ip address.
(Windows 10/11 has an app called 'Terminal' that you can find using the 'search' feature in your Start menu. It will open a terminal window for you.)
Your terminal address will differ, but here is an example:
You might see this warning:
That's normal. Type in 'yes' and press enter. After the change is made, you'll be returned to where you started.
ssh neon@<device ip addressagain to start the password update process. You'll be prompted to enter the password. The default password for Neon AI OS images is 'neon'. It will not show in the terminal window when you type passwords. Type in neon, and press enter. Follow the prompts to set a new password.
One more time, type in
ssh neon@<device ip addressand enter your password.
Your terminal prompt should change to show that you are accessing Neon on your Mark II device. For example:
Now Run the one-time update script
Update via on-device terminal
If you have a USB keyboard available, you can open a terminal on your Neon device
to start the update.
1. Connect a USB keyboard to your Neon device.
F1 to open a terminal.
3. Tap or click on the terminal.
4. Run the one-time update script
Run the one-time script
Run the following commands to download and run the one-time update script:
wget https://neon.ai/one-time-update bash one-time-update
Example of running wget:
(The https://neon.ai/one-time-update page is a friendly url which redirects to the longer one used in the example.)
Your Mark II display should change to show the Neon logo, and words showing its status. This may take a couple minutes, or longer depending on your connection speed. When you see the home screen return, you're good to go!
The update process may vary slightly as systems mature, but a description of the components is included here.
Neon Updates Skill
The Neon Updates Skill handles user requests to check for updates. If an update is requested, the skill will emit a message to start an update which the PHAL Plugin will handle. This skill is also where settings determine if pre-release versions are included in updates.
Core Updater Plugin
Updates are managed by the Core Updater Plugin
which is configured in Neon OS to run the
neon-updater SystemD service. The
neon-updater service is responsible for backing up
the current system and installing a newer version of
neon-updater service comes from
and is responsible for performing Python package updates. The service will stop
all core processes, backup the current Python environment, and then update
Python packages. After installation, the service will check that the core services
load before optionally rolling back failed changes and then restarting Neon.
