Hello, totally new here.

A friend asked me to install the energycoin app on his Rasberry Pi ( model 4)
First i tried: ubuntu-mate-18.04.2-beta1-desktop-armhf+raspi-ext4.img.xz.torrent ( not even load the sdcard boot)

second i try the 32-bit version of Ubuntu 19.10 , what did installed the package :

But it not runs.
The 19.10 version of ubuntu creates a User: ubuntu.
Yet, no desktop icon is shown.
if i browse to the file_system and choose from there: Desktop
The EnergyCoin icon shows up.
If i double-click   Nothing happens.
If i try to move it to the "desktop" , it say i do not have permissions.
If i goto properties->permissions and change permissions to user : ubuntu.
Still not works.

This is not for me, it is for a friend, i would like to succeed for him to install this Energycoin app ( he sells solar-panels, no idea if there is a relation with it).
Can someone help me out?

Thanks in advance!
Greetings Henry!
