[Solved] Starting MCServer on the RasPi

[Protectator]

Thanks for your answers !

I tried a few more times, but what you told me is what I already tried. Here's a few screenshots of what happens :

At start I tried to run it from the first folder :


But the only thing it does is to clear the console and to tell me I don't have the right to do it :
(Yeah, I'm using my raspi in french, "Permission non accordée" means "Not granted permission". And it's the same when I launch it using sudo)


But it seems like, as you said, I was doing it wrong, so I opened the MCServer folder to try to run it from here, but there's another problem :

When I launch screen, the console goes all black for ~2seconds, seems to display a message at the end but I'm totally unable to read it, it seems like it only keeps on screen during 1 frame, and then the console is cleared again, the message "[screen is terminating]" appears and I'm here again. If at least I could read the supposed error message it tries to show me... but I don't know what to do, here.
