AMD had release AMD GPU pro drive recently and I was trying to install that on my Leap15.3.
I'm not sure why when I added local downloaded drive to the repo, I got GPG sign warning and as tried to install got this error:
he following 2 NEW packages are going to be installed:
  amdgpu-pro-versionlist amdgpu-versionlist

2 new packages to install.
