Kolla Ansible Installation Issues

Hi everyone,

I'm a new OpenStack user from Indonesia, and for the past few weeks I've been having trouble installing OpenStack even though I've been following the steps in the link *https://btech.id/en/news/cara-menginstall-openstack-menggunakan-kolla-ansibl... https://btech.id/en/news/cara-menginstall-openstack-menggunakan-kolla-ansible/#*

So, it looks like I decided to do a reinstallation, but I don't know if I should uninstall the old one first or what.

Is there any guidance that can be given to me to do this reinstallation?

Thank you. Cakra Wirabuana
