Unable to start a headless application on Linux

Hi !

I've been looking around for information about that but wasn't able to find any real help so I post here.
I'm desperately trying to run a unity application in headless mode on a Linux private server.
I thought that this would be pretty straight forward: Build it with "Headless" checked, upload it to the server, run it.
But It crashes at start up for some reason. For test purpose, I'm using here an empty project with a simple scene containing a camera and a GO with a script that logs "Start !" when starting.

This is what the console look like when I start it:

Set current directory to /var/www/Uploads
Found path: /var/www/Uploads/Test.x86_64
Mono path[0] = '/var/www/Uploads/Test_Data/Managed'
Mono config path = '/var/www/Uploads/Test_Data/Mono/etc'
Player data archive not found at `/var/www/Uploads/Test_Data/data.unity3d`, using local filesystem
Aborted

And this is the log file:

Native stacktrace:

Debug info from gdb:


=================================================================
Got a SIGABRT while executing native code. This usually indicates
a fatal error in the mono runtime or one of the native libraries
used by your application.

Linux distribution info: Debian 8.8 x86_64

 

More information:

I tried using Unity 5.6 and 2017.1

It looks very much like this issue https://forum.unity3d.com/threads/ubuntu-headless-build-wont-run.451830/

"dpkg-query --show libc6" gives this output
libc6:amd64 2.19-18+deb8u10
libc6:i386 2.19-18+deb8u10

 

Same Problem here with Unity 2017.1 on Linux, the player data archive is not found.

What is the player archive anyway?
And what is the data.unity3d file?

I cannot find any Information for those two anywhere.

 

Well based on this post the data.unity3d file is not really the problem here: https://forum.unity3d.com/threads/player-data-archive-not-found.464417/#post-3018952. Looking at the stacktrace, it looks more like a crash in the mono library but I can't find to solve it...

 

Bump, still having the issue

I tried with the new experimental C# runtime version, with no better result.

It is necessary for me to be able to run a headless application on my Debian server as a game server. Any help appreciated

 

I've just tested a build on debian 8.7 and debian 9.1 - both functioned as expected.
It's possible that the issue is specific to your project or environment.
Your best bet is to file a bug report with your project attached.

 

Hi Tak, thanks for your time and the tests you did.

I'll file a bug report with an empty project and as much info as I can.

 

Seems to be a standard issue when running headless, Its not even an issue. Just a warning that it's running without graphics if anything.
