The game installed and started fine, I can create my "profile" and see the intro cinematic.

Then, the tutorial go for a bit and ask me to use the Reader. Clicking on the reader instantly crash the game.

Starting the game from the console show a message about Illegal Instruction in Orwellx86_64, but no details.

Side note that may have its importance, I am not running Ubuntu, but Debian (which is the base of Ubuntu, and as such compatible on about everything).

I will add the report when I ll found where to store it (html wouldn't be useful here).

Complete log of the game:

You're ahead of me! Mine is crashing on start; I can't even get to the opening screen. (Running Debian 8)

I have been able to run the game (kind of slowly) in virtualbox running Ubuntu 16.04. I'm just downloading a copy of Debian 9 RC to see if the problem will be fixed with the upcoming release.
