Why we're focusing on Ubuntu?

Most of our installation and maintenance documentations seems to be more based on ubuntu distro.
Even the installation script for CentOs is not working.
Why are you guys avoiding CentOs completely?
Most of the business users are still using centos because of its stability.

We aren’t intentionally avoiding any distro. We ourselves use CentOS in production extensively. I’d suggest you to tell us the problems you’re facing during installation and we can work towards fixing it.

Alternatively you can create a new issue here.
