The official Teams desktop app for Linux was retired in December 2022. Microsoft dropped it in favor of a Progressive Web App (PWA), but things haven’t quite gone according to plan. The PWA that was supposed to replace the electron app lacked various features and was unstable. Worst of all, many users don’t get the option to install it at all, even now. As of April 2023, the most reliable way to install Teams in Ubuntu is with a third-party snap called teams-for-linux. It’s not perfect either, but it’s generally better than any other option. Install teams-for-linux Snap Teams For Linux is an unofficial Microsoft Teams client developed by Ismael Martinez. It wraps the web app as a standalone desktop app using Electron. As such, you’ll have to select the Use web app option after installing and logging in to Teams. Install from Terminal You can install the latest stable version with sudo snap install teams-for-linux Or you can download the beta (edge) version instead by specifying the channel. sudo snap install teams-for-linux --channel=edge Afterward, you can launch Teams from the Applications menu, or directly from the terminal by entering teams-for-linux Install Teams Graphically The terminal is as quick as it gets, but if you’d prefer a graphical install method, you can also install this snap from the Ubuntu Store. Open the Ubuntu Software app and search for ‘teams’. Open the Teams For Linux page, select the channel, and press Install. After installing it, you can launch the app from the Applications menu. Teams Progressive Web App One of the main reasons for Microsoft’s switch to the PWA is cross-device compatibility. PWAs can be installed and run on various devices from the same codebase as they’re web-based. Generally, anyway. This hasn’t gone too well in the case of Teams. If you go to the Teams website and log in, you’ll land at the live web version. If you’re running a Chromium-based browser like Google Chrome or Edge, you may get the option to install the PWA from the URL bar. But if you’re on Firefox or any other non-Chromium browser, the PWA won’t be available. You’ll have to use the snap or the web version. In some cases, even Chromium users won’t be able to install the PWA, and there’s no way to bypass this at the moment.
