Ubuntu Won't Install Over Existing Linux Distros

I'm trying to install Ubuntu on a system I haven't used since 2014 and it just isn't happening. It originally had Kali and OpenSUSE installed on separate physical disks and I honestly couldn't care less about either installation. Ideally, I'd like them both gone. I tried installing Ubuntu automatically over the existing OpenSUSE install but Ubuntu wouldn't load. Next, I tried using Boot Repair but it just canceled itself. I then tried installing Ubuntu on the other disk alongside Kali but that won't load either. Here's the paste bin link is http://paste.ubuntu.com/p/Cc3ydcW4Sm.

Any help at all would be deeply appreciated.
