Advanced Configuration
Troubleshooting
Linux
steamservice.so missing/failed to load
This is a common issue with a fairly easy fix.
The reason for this error is that SteamCMD doesnt place the file in the folder it should, as the games typically look for it there. So what you need todo is the following.
Create a symlink (shortcut) for each of the files like this: (run each seprately)
ln -s /home/your_user/.local/share/Steam/steamcmd/linux64/steamclient.so /home/your_user/.steam/sdk64/ ln -s /home/your_user/.local/share/Steam/steamcmd/linux32/steamclient.so /home/your_user/.steam/sdk32/
Replace your_user with the username you are using.
