Unable to locate package while installing vulkan and nvidia-graphics-drivers

Question

I have been trying to set up UnrealEngine4 for my ubuntu 18.04.5 LTS system. I've followed this tutorial, https://docs.unrealengine.com/en-US/SharingAndReleasing/Linux/BeginnerLinuxDeveloper/SettingUpAnUnrealWorkflow/index.html I have done everything up until launching UE4 with "./UE4Editor". In this step, UE4 opens up but says that there is no Vulkan installed and closes down again. I have tried to install the drivers and vulkan with this tutorial, https://linuxconfig.org/install-and-test-vulkan-on-linux . The problem here is that when I type "$ sudo apt install nvidia-graphics-drivers-396 nvidia-settings vulkan vulkan-utils" in the terminal, it gives the following error.

Reading package lists... Done Building dependency tree
Reading state information... Done E: Unable to locate package nvidia-graphics-drivers-418 E: Unable to locate package vulkan

No idea how to fix this. Please help.

Answer 1

That driver is proprietary. Consult the manual how to install it.

vulkan package is not something that exists. Probably meant to be libvulkan1 , but should be installed as dependency.
