Minecraft Server Linux error?

I'm currently installing a minecraft server on a linux debian 10 server but can't access the minecraft console and the server does not seem to start either

minecraft @ vps: ~ $ ./start.sh

minecraft @ vps: ~ $ screen -r minecraft

There's no screen to be resumed matching minecraft.

start.sh says: screen -AmdS minecraft java -Xms1024M -Xmx1024M -jar /home/minecraft/spigot-1.12.2.jar

and in the euler.txt: eula = true

With the command screen you call up a graphical interface, I suspect you are connected via ssh and ssh has no graphical transmission and can therefore not be output because minecraft (or the server) can't find a valid display

No, screen is not a graphic application, but a terminal multiplexer.

And then how can i use the command?

Can you please start that without a screen command and then insert the log output here? That would help.

I started the server but nothing happens, only the .jar file, the .sh and the eula.txt remain

What if you just

java -Xms1024M -Xmx1024M -jar /home/minecraft/spigot-1.12.2.jar

./start.sh: line 1: java: command not found Comes as an error message

It works, I reinstalled java and it works.

No problem.
