-Which install file for Minimserver 2 Pi3b+ with Ubuntu

[MDF]

Hi, I have been running Minimserver2 on a linux laptop but now wish to move it to a headless rasberry pi to enable it to be left running. I have 2 questions;

1. Which install file is the correct one for the rasberry pi 3b+ running ubuntu server 20.04.1, arm 64, arm hard float or arm soft float?

2. Is there a guide to installing minimserver2 and minimstreamer on a headless system, I think I can probably install the files with my limited command line skills but I am a bit unsure how to get the files on the pi in the first place? Is the best way to mount the pi home directory to my linux laptop, would that have the right permissions to move a file? I suppose there isn't a remote GUI for ubuntu that I can run on my desktop pc? I have tried loading xubuntu before from my other pi3 which I use as an audio renderer but it would not play with my hdmi monitor which stayed blank. If I can do this headless it would be preferable to a load of monitor troubleshooting first.

I don't want to buy a license until i know I can get all this up and running. I guess I can do that via minimwatch on my pc?

Any help from a pi ubuntu expert would be very much appreciated.
