Looks like the link points to a different challenge

Nice challenge, I don't know if intentional but the libc version is too recent. It was at least giving me some trouble so I had to do my attempts on the server.

Yes, I'm aware of this, but to be honest, it is hard to use libc version that everyone uses. You can always use docker (like ubuntu 20.04) or tools like patchelf (and replace needed libc and ld to your system ones).

Thanks for the hint, I'll look into patchelf.
