Tested on Ubuntu 21.10
- Activate Proton in Steam settings
- Install Anno 1800 within Steam
- If you run the game now it will show an error message that Ubisoft Connect could not be found
In my case the game was installed on another drive called GamesSSD
so paths may vary. Also change the username.
You need the path to your steamapps
folder for the SteamLibary the game was installed in.
- Download Ubisoft Connect Windows Installer
- Set enviroment variables, both paths are the same
export STEAM_COMPAT_CLIENT_INSTALL_PATH=/media/user/GamesSSD/SteamLibrary/steamapps/compatdata/916440
export STEAM_COMPAT_DATA_PATH=/media/user/GamesSSD/SteamLibrary/steamapps/compatdata/916440
- Run the installer with the included proton
~/.steam/root/steamapps/common/Proton\ -\ Experimental/proton run /home/user/Downloads/UbisoftConnectInstaller.exe
