dpkg: error processing package yunohost (--configure):

Hello.
I am trying to install yunohost on a live debian11 which can be downloaded from here:

https://cdimage.debian.org/debian-cd/current-live/amd64/iso-hybrid/

yunohost is a web content manager that is very easy to use and for this reason it is necessary to create a live iso to be able to spread it.
Steps to reproduce:
Once the debian 11 live iso is loaded in Cubic, and the
terminal in chroot, you have to:

Open another linux terminal to go delete the file <Custom-root-path>/etc/resolve.conf

and in cubic terminal give these commands:
apt remove resolvconf
apt install resolvconf

and finally give the installation command of yunohost

curl https://install.yunohost.org | bash

then the script will update the system until it reaches the error that can be seen in the log below

Setting up yunohost (11.0.10.2) ...
System has not been booted with systemd as init system (PID 1). Can't operate.
Failed to connect to bus: Host is down
