As of this writing, the newest version of the cPanel installer poses some additional requirements for new installations:
- cPanel must be installed on target version 11.40
- For any Redhat-based OS (RHEL, CentOS, CloudLinux), you must be on version 6
If your server does not meet these requirements, you have two options:
A. Install version 11.38 as a target version
To do this, you’ll need to create a file called /etc/cpupdate.conf before cPanel is installed on your server. In this file, add:
CPANEL=11.38
Then run the installer normally:
wget http://layer2.cpanel.net/latest
sh latest
From here, you can upgrade to the latest version by replacing “CPANEL=11.38” with:
CPANEL=stable
or the version you want to upgrade to, ie:
CPANEL=11.42
Then run /scripts/upcp to update.
B. Force the installation
Download the installer and run with the –force flag:
sh latest --force
Note that these instructions will become invalid once cPanel 11.38 becomes EOL. The restrictions are intended to encourage system administrators to run the latest software.
