2023-06-27 21:42:38  128 [7955] (FATAL): The system failed to run the /usr/local/cpanel/scripts/cpanel_initial_install script.


The cPanel installer will fail if it cannot create the is_ea4 touch file or create or update the EA4.repo file. When this occurs, the files must be created manually, and the repo file must be manually updated.


  1. Access the server's command line as the 'root' user via SSH or "Terminal" in WHM.
  2. Create the /etc/cpanel/ea4/is_ea4 touch file.
    touch /etc/cpanel/ea4/is_ea4
  3. Open /etc/yum.repos.d/EA4.repo in your preferred text editor.
  4. Ensure that the file contains the following.
    name=EA4 ( EasyApache 4 - c$releasever )
  5. Run the following command to restart the cpanel_initial_install script.
    export CPANEL_BASE_INSTALL=1;/usr/local/cpanel/scripts/cpanel_initial_install
  6. Once the script finishes running, run the following command.
  7. Verify that all of cPanel's core packages have been installed.
    /usr/local/cpanel/scripts/check_cpanel_pkgs --fix
  8. Run the upcp script to verify that there are no further issues with the installation.
    /usr/local/cpanel/scripts/upcp --sync
