Hi there,

i have installed a completly fresh Rust Dedicated Server on 20.04 LTS Ubuntu and cannot get the compiler getting loaded successful. There is no Mono installed (checked with apt list --installed | grep mono)

The vanilla server starts up but oxide does not compile any plugin. i have tried without and with a single plugin (ImageLibrary) but nothing seems to work.

The Server shows these lines while trying to run the compiler:

23:04 [Error] Exception while starting compiler version : (Exception: Magic number is wrong: 542)

23:04 [Error] BaseException: (Exception: Magic number is wrong: 542)

I have installed the server with a own user and chmod +x the Compiler in the directory too after checking the Log-Files. Even executing the server as root does not solve the problem.
