Unable to log in, Cannot run program "%USER_PROFILE%/Downloads/natives/faf-uid", No such file or directory

[matusnovak]

Describe the bug

When trying to log in the following error appears:

Caused by: java.io.IOException: Cannot run program "%USER_PROFILE%/Downloads/natives/faf-uid": error=2, No such file or directory

It looks like it is trying to access %USER_PROFILE% directory via an environment variable, but that is not a valid Linux environment variable, and that directory does not exist.

Is there a workaround?

To Reproduce
Steps to reproduce the behavior:

• Download the latest client v2023.7.1 (faf_unix_2023_7_1.tar.gz)
• Log in

%User_Profile% is just log masking. You need to properly set the natives directory on Linux. You can refer to the community notes on wiki.faforever.com

Oh I see. Thanks. I thought that was some unexpected Windows environment variable.
