Is There an Official Microsoft OneNote App for Ubuntu Linux?

Access OneNote on Ubuntu through OneNote for the web or a browser-installed web app, and use trusted Linux alternatives for local productivity.

Why There Is No Native OneNote App for Ubuntu

Users searching the Ubuntu Software Center or apt repositories for Microsoft OneNote will come up empty-handed. While Microsoft offers native desktop applications for Windows and macOS, as well as mobile apps for iOS and Android, there is no official installable `.deb` package or Snap for the OneNote desktop client tailored for Ubuntu or any other Linux distribution.

Quick Answer: Use OneNote Web or the PWA

Microsoft does not currently provide a native desktop version of OneNote for Linux. The official and most stable workaround is to use OneNote on the web via a modern browser like Firefox, Google Chrome, or Microsoft Edge for Linux. Alternatively, you can install third-party community wrappers, provided you verify their security first.

Why Microsoft Doesn’t Offer a Linux Client

• Market Prioritization: Microsoft focuses its Office suite development on platforms with the largest consumer and enterprise desktop market shares (Windows and macOS).
• Linux Fragmentation: The Linux ecosystem features numerous distributions, package managers, and desktop environments, making it resource-intensive to develop and maintain a unified native desktop app.
• Cloud-First Strategy: Microsoft has shifted much of its cross-platform development focus to web-based technologies, encouraging non-Windows users to rely on Microsoft 365 cloud applications.

Step-by-Step: Set Up OneNote Web and the PWA

The most secure and feature-rich way to use OneNote on Linux is through the official web application. You can turn this into a Progressive Web App (PWA) so it behaves like a native desktop app with its own window and icon.

1. Open a Chromium-based browser (such as Google Chrome or Microsoft Edge for Linux) on your Ubuntu machine.
2. Navigate to www.onenote.com and log in with your Microsoft account.
3. Once your notebooks load, click the three-dot menu icon in the top-right corner of your browser.
4. Select Save and share (or More Tools depending on your browser version), then click Install page as app... or Create shortcut.
5. Check the box that says Open as window and click Create.
6. You will now have a OneNote icon in your Ubuntu application launcher that opens in a dedicated, distraction-free window.

Alternative Solutions for Third-Party Desktop Wrappers

If you prefer not to use a standard browser window, the Linux open-source community has developed "wrapper" applications. These apps encapsulate the web version of OneNote into an Electron-based desktop client.

1. Search Snapcraft or Flathub: Look for community projects like P3X OneNote in your software manager.
2. Verify the Source: Because these are third-party apps, strictly check the developer's reputation, recent update history, and user reviews before installing.
3. Install via Terminal (Example for Snap): If verified, you can usually install these via a terminal command such as sudo snap install p3x-onenote.
4. Security Warning: Never enter your Microsoft credentials into untrusted software. Ensure the wrapper directs its login sequence through the official Microsoft authentication servers.

Working with WPS Office: A Native Linux Productivity Alternative

While WPS Office does not feature a direct 1:1 clone for digital notebook syncing like OneNote, it stands out as one of the best native productivity suites available for Ubuntu Linux. If your primary frustration is the overall lack of Microsoft Office desktop apps on Linux, WPS Office natively handles Word documents, Excel spreadsheets, and PowerPoint presentations with industry-leading formatting compatibility. It offers a smooth, installable desktop experience for your local documents without relying on web browsers or third-party workarounds.

Tips for Installing Office Software Safely on Linux

• Stick to Official Repositories: Whenever possible, download browsers and tools directly from the Ubuntu Software Center or verified APT repositories.
• Keep Browsers Updated: Since you will rely on the web version of OneNote, ensure your browser is always up-to-date to maintain maximum security and performance.
• Enable Offline Syncing in Browser: Check your browser settings to ensure site data can be cached, which may help preserve your notes if your internet connection temporarily drops.
