1. Update cloudlinux-release package from rollout slot

# dnf –enablerepo=cloudlinux-rollout-4-bypass install cloudlinux-release

2. Do system upgrade

# dnf update

In about 2 weeks, CloudLinux OS 9.3 will be available from general repository  and could be updated just with following command:

CloudLinux 9.2, 9.3  and cPanel integration notes

Starting from 11.116.0.1, cPanel is fully integrated with CloudLinux 9  ( 9.2, 9.3 and next), so flag –experimental-os=almalinux-9.2 is not needed anymore

Note! If you have a server with already installed cPanel + CloudLinux via  experimental flag  –experimental-os=almalinux-9.2 , as we described  here, it is highly recommended to reinstall the server from scratch to avoid unexpected behavior.

Note! Until the version cPanel 11.116.0.1 is not in the Stable Release, use the next instructions to install cPanel on CloudLinux 9 latest versions. 

1. Update the /etc/cpupdate.conf as described here, and set:  CPANEL=current2. Start cPanel installation process 

cd /home && curl -o latest -L https://securedownloads.cpanel.net/latest && sh latest
