      Pre-requisites

      1. Testing using PHP 8.0
      2. Block network access to download.moodle.org, for instance, adding this in your local /etc/hosts file: 

        127.0.0.1    download.moodle.org

      3. The test assumes a valid path of /var/www/moodledata to use as data root - modify as appropriate for your system
      4. If you're using a Moodle folder with config.php, you'll need to remove it.

      Testing

      1. Execute the following command on a terminal:

        $ php admin/cli/install.php --lang=it --chmod=2777 --wwwroot=http://localhost:8000 --dataroot=/var/www/moodledata
        

      2. Press return to confirm (it) default
      3. Press return to confirm (2777) default
      4. Press return to confirm (http://localhost:8000) default
      5. Press return to confirm (/var/www/moodledata) default
      6. Confirm no error/debugging notice was triggered, displaying the following:

        Undefined constant "NO_DEBUG_DISPLAY" in /var/www/html/lib/weblib.php:3270
        

      7. Confirm you see the following text informing you that the lang pack could not be downloaded:

        <p>Lo scaricamento delle componenti non è andato a buon fine. Verificare le impostazioni del proxy. L'estensione PHP cURL è fortemente consigliata.</p>
        <p>Devi scaricare manualmente il file <a href="https://download.moodle.org/download.php/langpack/4.2/it.zip">https://download.moodle.org/download.php/langpack/4.2/it.zip</a>, copiarlo in "/var/www/moodledata/lang" e decomprimerlo.</p>
        

      8. Press n to exit the installer
      9. Re-enable network access to download.moodle.org
      10. Run the CLI command again
      11. Proceed to the step after confirming the location of data root:

        == Cartella dati ==
        inserisci un valore oppure premi Invio per usare il valore di default (/var/www/moodledata)
        

      12. Confirm that the Italian language pack was successfully downloaded and extracted to /var/www/moodledata/lang/it
      13. Complete installation

    Description

      Installing a brand new 39 I got this message on the step when Moodle tries to download and install the user-selected language pack.

      Warning: Use of undefined constant NO_DEBUG_DISPLAY - assumed 'NO_DEBUG_DISPLAY' (this will throw an Error in a future version of PHP) in /var/www/html/lib/weblib.php on line 3220
       
      Warning: Use of undefined constant NO_DEBUG_DISPLAY - assumed 'NO_DEBUG_DISPLAY' (this will throw an Error in a future version of PHP) in /var/www/html/lib/weblib.php on line 3228
      
      

      The error only occurs if the download of the language pack fails (for example because of selinux, or network access restriction)
