i reinstalled steam and dont stave together but still getting the same error.
and the file main.lua is in the folger data/scripts

-rwxrwxr-x 1 steam steam   7876 Jan  9 01:47 main.lua

and steam is the user i use to start the server.

some one any idea how to fix this error?

[Killerbear_02]

i followed this guide

but i could not execute the command line

dpkg --add-architecture i386

because my server is running  Ubuntu 12.04 LTS
and reffering to this thread: https://answers.launchpad.net/ubuntu/+source/dpkg/+question/221647
there is not support for dpkg -add-architecure on Ubuntu 12.04 LTS

So i will try to upgrade my server the a newer ubuntu version and hopyfully everything works fine.
(But first do a backup ^^)
