'miniONE --verbose --lxd' stuck on 'Installing OpenNebula packages'

I am trying to install miniONE on Ubuntu 20.04 KVM VM but ‘miniONE --verbose --lxd’ command stuck on ‘Installing OpenNebula packages’:

bash minione --verbose --lxd

Enable NAT over eth0
Modify AppArmor
Install OpenNebula LXD node

I would appreciate any hint on how to debug and fix that issue!
