Hello,

Trying to compile Unreal on Ubuntu, get this compile error:

```

```

Is this version incompatibility issue?  
Unfortunately I can’t find information anywhere is Ubuntu 16 supported, what version of Vulkan in required here.

Thank you.

You have to updated your system drivers as well.

What version of drivers/Ubuntu is expected? Is Ubuntu 16.04 supported/will work with?

Well, had to come to answer myself. UE4.23 ships with vulkan-1.1.106 which is _embedded_ with UE4.23 itself. So it all supposed to work out of the box unless:

- you don’t have video drivers that support Vulkan - just install your latest
- you have made local installation of different Vulkan **SDK** version and added path to it into your bash.rc or profile. This will override Unreal paths and will break the build. More on it here: [F:/UnrealEngine-release/Engine/Source/Runtime/VulkanRHI/Private/Android/../VulkanLoader.h(6,10): fatal error: 'vulkan.h' file not found - Rendering - Epic Developer Community Forums](https://answers.unrealengine.com/questions/818473/view.html)

I installed SDK from [LunarXchange](https://vulkan.lunarg.com/sdk/home#linux) (you’re looking for 1.1.106 version), but I cannot say was it essential to be installed or not now.

And yes, UE4.23 works on Ubuntu 16.04.

Which graphics card are you working with? Is it supported by the nvidia drivers? See [Vulkan Driver Support | NVIDIA Developer](https://developer.nvidia.com/vulkan-driver)

If it is supported, then install latest nvidia driver (418.43 works for me) and vulkan drivers.
