Impossible to run dedicated server under linux

Hi , here is the tutorial i try to follow :
It’s valve official tutorial so i guess it must be good .
here is the problem, once i’ ve installed Rust dedicated server on my dedicated server here are the files i get when i type “ls” command in the rust directory :
rust_server.x86----> im on a 32 bit system so i try ./rust_server.x86 but then it says : “./rust_server.x86: error while loading shared libraries: cannot open shared object file: No such file or directory”

So if anyone as any idea on how i can run it just tel me, any help would be much apreciated.
Thanks everyone :wink:

Rust server files arent released for public yet…

Allright thanks for the help !
