3.3.9 and 3.3.10 PHP Fatal Error launching installer.php on Ubuntu Server

[marco-03091991]

What is the bug?

I cannot install lizmap through installer.php, I tried both version 3.3.9 and 3.3.10, launching the installer appear a PHP Fatal Error. I've tried to find out some problems in the PHP file (like different port or something like that), but I'm not so proficient in Jelix or PHP. How can I install Lizmap? Best reguards Marco

Do you have installed php-xml or php7.4-xml package ?
