Raspberry Pi OS added a Microsoft repo. No, it’s not an evil secret

We were recently alerted to something of a tempest in a teapot: When the Raspberry Pi Foundation made it easier to install Microsoft’s Visual Studio Code development environment, some Linux users mistook it for a sort of Mark of the Beast, with concerns being raised about telemetry and “what Microsoft repo secretly installed without your knowledge.”

It’s true that an update recently pushed to Raspberry Pi OS added a Microsoft repo to Raspberry Pi OS systems—but it’s not true that it added any actual packages whatsoever.

Investigating the changes

Just to the left of the 40-pin GPIO header, you can see the Pi 400’s SD card slot. Want to play with two different distros without the hassle of uninstalling and reinstalling when you switch? Just use two different SD cards! (credit: Jim Salter)

Luckily, my own Raspberry Pi 400 was running Ubuntu, not Raspberry Pi OS, which made it easy to switch back and see what changes occurred in the system. Equally luckily, the Raspberry Pi 400 is almost ideally suited to distro-hopping—all I needed to do to get a pre-update version of Pi OS running was to power my Pi off, swap SD cards from the Ubuntu card I had been using to my old Pi OS card, and then fire it back up. Presto, a pre-update Pi!
