when downloading the Linux Ubuntu Driver for Graphics Card RX560
i noticed the following passage:
To use the Vulkan driver in this stack, Vulkan SDK version v18.104.22.168 needs to be installed. The SDK can be downloaded from: https://vulkan.lunarg.com/sdk/home
However, there is no such version 22.214.171.124 to be downloaded from that page.
Either version 1.1.108 (or below) or 1.1.114 (or above) is possible.
