Forge 1.12.2 Server on Ubuntu, Forge.[xxx].jar In accessible

[Jamiemuk]

Hi guys, im trying to set up a forge modded server on Ubuntu and hit a bit of a wall, i have minecraft with forge 1.12.2 currently running my chosen modpack which works in single. I have the forge server downloaded and installed but when following guides they want to to run the forge.xxx.jar, it tells me this file cannot be accessed but it allows me to run the minecraft.xxx.jar to start a LAN Vanilla server (this is a working server just awaiting configuration for other users to connect).

I can either find really good guides on how to use forge on windows, or guides to set up servers on linux that dont use forge, if anyone has abit of knowledge that could help or even a point to some resources that could help would be appreciated

 

thank you
