Cities: Skyline won't start on Ubuntu 18.04

[tom16wilder]

Cities: Skyline will not launch when I click on 'Play' in my steam library. It is odd, because yesterday it was working perfectly, but this morning, it is not.

Things I have tried:

• Reinstalling steam and the game
  
• Turning off overlay
  
• Adding -force-opengl to the set launch options

Here is the error.log file:

What is interesting is there doesn't seem to be the games name in this line, 'Game update: AppID 255710 "", ProcID 2645, IP 0.0.0.0:0'. But is that significant?

Any help would be great. I really do not want to buy Windows.

Thanks

Hi! Unfortunately I have no solutions to offer but I am having the exact problem with the same errors in the log file. It was running beautifully on Thursday night. Yesterday? Toast. Not sure what happened. Anyone have any suggestions?

Oh! I was able to find a solution after several hours of trying to fix this. Follow this guide on how to bypass the Paradox Launcher: https://steamcommunity.com/sharedfiles/filedetails/?id=1976349559

Worked a treat. Super easy on Linux. Enjoy your city building!
