Unable to install Kibana using RPM

I want to run the Kibana in the background.

So, I am trying to install Kibana using RPM.

I followed the instructions in this page - https://www.elastic.co/guide/en/kibana/current/rpm.html

I executed the below 3 commands:-

wget https://artifacts.elastic.co/downloads/kibana/kibana-7.4.0-x86_64.rpm
shasum -a 512 kibana-7.4.0-x86_64.rpm 
sudo rpm --install kibana-7.4.0-x86_64.rpm

When I executed the last command I am getting the below error message.

/home/software# sudo rpm --install kibana-7.4.0-x86_64.rpm
rpm: RPM should not be used directly install RPM packages, use Alien instead!
rpm: However assuming you know what you are doing...
error: Failed dependencies:
        /bin/sh is needed by kibana-7.4.0-1.x86_64

Are you trying to install an RPM on Ubuntu? I'd recommend using the deb package. That should allow you to run it in the background too, as a service.
