I think I need to update my compiler

Are you missing files in this folder?

The compiler is downloaded automatically when the server starts. If it isn't downloading, you'd need to figure out why the connection is blocked for it. As an alternative, you can manually download (should only be temporary) the compiler from https://umod.org/community/general-support/10494-manual-download-for-compiler?page=1#post-2

My server is running on linux.

I have the files on the picture.
Their owners are root.group is QQ.
i‘m not login root.
root downloaded the compiler manually and shared the permissions to me.
I just built the server following the wulf tutorial.
