Buka doesn't load on Ubuntu 18.04 about buka HOT 6 CLOSED

When trying to open the application via command line I get the following error

No schema files found: doing nothing.
[1]    9604 illegal hardware instruction (core dumped)  buka

Same problem. At the moment I solve it by installing the .deb package from releases.

from buka.

it works fine, I installed with deb file (Buka_1.0.0_amd64.deb)

from buka.

I have Ubuntu 18.04.4 LTS GMONE 3.28.2:

1. Download and install Buka deb
   sudo dpkg --install Buka_1.0.0_amd64.deb
2. install gconf-service
   sudo apt install gconf-service
3. Fix dependenciens
   sudo apt --fix-broken install

It works for me

from buka.

Same on 19.10, but I don't get the schema error, just illegal hardware instruction. It makes me very curious what it is trying to do, but I'm not motivated enough to figure out how to debug a snap app. I do appreciated having a confined snap app, but not much use if it doesn't work!

from buka.

Works for me too

from buka.

Not working for me.
