For Tropico 6 the Update Nueve "Guagua" and another (paid) DLC called "Spitter" have been released for Linux on Steam.

Description of the DLC:

It’s all about the fame and prestige. Nobody knows this better than a self-declared despot...uh, statesman, such as El Presidente. Tropico 6’s second DLC skyrockets you into the world of stardom and illustriousness. Interact with superstars by using Spitter, the only short message social networking app officially approved by the Tropican Ministry for Modern Communications & Smoke Signals. Court the stars to gain their support, unlock their individual strengths and in turn receive even more respect and adulation from your subjects. But beware - fame and money can also attract some seriously shady types…
At the heart of the DLC is the new Spitter mechanic, which allows you to interact with celebrities and faction leaders to increase your standing. Use new buildings like the Rehab Center or Beauty Farm to attract celebrities and make them permanent citizens of Tropico. Plus, enjoy even more new content with three new music tracks, additional customization items and a new trait for El Prez.
