I have the same issue on 4.14 and 4.15 I am trying to package a linux version of my game.
I am following these instructions
[Linux Development Requirements for Unreal Engine | Unreal Engine 5.1 Documentation][1]
I downloaded the toolkit and set my environment vairables but when I get to the “Setting up the Linux Build Configuration” I cannot find any of the files refrenced
It says to run [UE4 ROOT]/Setup.bat
and gives an example path o “Unreal Engine\UnrealEngine-realease\Setup.bat”
Which I think is “C:\Program Files\Epic Games\UE_4.15” on my machine but there is no setup.bat just a few folders
Clearly I am missing something
