Hello everyone!

I’m currently developing a plugin and I’d like to make it compatible with Linux. So I’ve installed Linux on my PC, grabbed version 5.1.1 of the Unreal Engine and dotnet 6. I can now launch the Unreal Engine and create a blueprint project. When I try to compile a C++ project, generate project files or package a blueprint project, I get the following errors

Package Blueprint Projet
PackagingResults: Error: System.ComponentModel.Win32Exception (13): An error occurred trying to start process ‘/media/ligs/Data/UNREAL/Linux/UE_5.1/Engine/Binaries/Linux/UnrealPak’ with working directory ‘/media/ligs/Data/UNREAL/Linux/UE_5.1’. Permission denied

Compiling C++ Project
An error occurred while trying to generate project files.

I’m relatively new to linux and I must admit I’m a bit lost. I understand that there is a permission problem but I don’t know how to solve it… Can an experienced Linux user help me? Thank you for your help.
