Linux Version Of Microsoft Teams Is Now Available
Microsoft have made a "public preview" a native Linux version of their Teams collaboration software available as .deb and .rpm packages. The announcement describes it as "the first Microsoft 365 app that is coming to Linux desktops".
GNU/Linux users who have wanted to use Microsoft Teams have so far been limited to using Microsoft's web browser version. The "public preview" release of a native Linux client gives Linux users the option of using the full desktop version of the collaboration software for people wearing suits. Competitor Slack has had a Linux beta version available for some time now.
Microsoft's Teams announcement states that the client will eventually
"support all of Teams’ core capabilities. Teams is the hub for teamwork that brings together chat, video meetings, calling, and collaboration on Office 365 documents and business processes within a single, integrated experience."
It sounds a lot like Microsoft is planning to release native Linux version of their Office 365 office suite and other "Microsoft 365" software in the not too distant future.
Microsoft has already confirmed that it will release a Linux-version of it's Chromium-based Edge browser. The new Chromium-based version of their Edge browsers will be released for Windows and macOS on January 15th, 2020. The Linux version will not be released along with the Windows and macOS versions, it will instead be released "at a later time".
We did test that their Teams preview installs and executes. We did not go beyond the login screen which requires a "Work, School or Microsoft Account".
The Teams Linux version is available from the regular Teams download page as .deb and .rpm packages. There are no snap or flatpak or AppImage versions available. Microsoft lists Ubuntu 16.04 LTS, 18.04 LTS, Fedora 30, RHEL 8 and CentOS 8 as supported distributions. Installing their .deb or .rpm Teams package will add a Microsoft repository to the distributions sources list. Their separate linux installation instructions page mentions that the Teams package will be updated monthly.
Microsoft Teams is only available in binary form. It is not released as free or open source software.
