I just rented a Debian 10 server or a V-Server and set it up with Minecraft (it's a PaperMC server), everything worked out fine, but now I want to install some plugins and unfortunately I can't do that someone help the OS is Debian 10
As Dragonplayer147 already wrote. How to do it normally. Download Plugin.jar from e.g. Spigot and drag it into the Plugins folder. If FTP doesn't work, you can actually do that via SFTP. You don't have to install anything extra. If you still need a tut to set up the MC server, this is definitely helpful: https://www.bennetrichter.de/anleitungen/minecraft-server-linux/
