OVH offers installation files for its customers, but what happens to these files?

When I try to install CentOS 7 with Cpanel on my system, the quota system is not allowed to be activated.
It is possible that upgrading to Cloudlinux will correct the issue, but it does not work.

Afterward, I tried to reinstall the software
Initially, I installed Centos 8 (OVH image), converted to Cloudlinux (work) and then installed Cpanel - the system crashed, and I had to restart it.

The CloudLinux support team informed me that the problem was the fault of OVH. How can I proceed?

The last four days have been hell for me!! I haven't been able to move!

What are the steps for installing Cloudlinux + Cpanel on a dedicated server?
Do you have any suggestions?
