I'm trying to run my server on 1.10, but every time, I keep getting this error code:

I have no idea what it means, but if anyone does, could you please help me by telling me what's wrong?

Thanks.

Are you running the server right. By installing the server with the installer. Error: Missing libs.

What do you mean? I'm not installing the server with minecraft.1.8.9.jar or Forge.1.8.9.jar (it's a modpack). Should I?

(sudo java -Xmx1g -Xms1G -jar minecraft_server.1.8.9.jar nogui)

(sudo java -Xmx1g -Xms1G -jar minecraft_server.1.8.9.jar nogui)

I'm using "sudo java -Xmx1g -Xms1G -jar FTBserver-1.10.2-12.18.3.2281.jar nogui"
