Wizard broken: TypeError: 'NoneType' object is not iterable

Issue

After installing CloudLinux, the Wizard is not working with the following error:

Traceback (most recent call last):
File "/opt/alt/python37/lib/python3.7/site-packages/clwizard/wizard.py", line 94, in run
self._get_initial_status()
File "/opt/alt/python37/lib/python3.7/site-packages/clwizard/wizard.py", line 255, in _get_initial_status

for it in self._php_interpreters_list():
TypeError: 'NoneType' object is not iterable

Environment

• cPanel
• CloudLinux OS
• PHP
• CloudLinux Wizard

Solution

Install any native PHP version (for cPanel servers, any EA-PHP). It can be done via EasyApache or command-line (in this example, we're using EA-PHP 8.0):

# yum install ea-php80

Cause

This will typically happen on new servers, and the issue lies in this line:

 File "/opt/alt/python37/lib/python3.7/site-packages/clwizard/modules/php.py", line 154, in initial_status
for it in self._php_interpreters_list():
TypeError: 'NoneType' object is not iterable

The "_php_interpreters_list()" function is returning "None", which is not considered an empty iterable. To avoid this error, there must be at least one PHP interpreter available on the system.
