Problem 1 - phpunit/phpunit[9.5.10, ..., 9.6.x-dev] require ext-dom * -> it is missing from your system. Install or enable PHP's dom extension. - Root composer.json requires phpunit/phpunit ^9.5.10 -> satisfiable by phpunit/phpunit[9.5.10, ..., 9.6.x-dev].
To enable extensions, verify that they are enabled in your .ini files:
\- /etc/php/7.4/cli/php.ini
\- /etc/php/7.4/cli/conf.d/10-mysqlnd.ini
\- /etc/php/7.4/cli/conf.d/10-opcache.ini

You can also run php --ini in a terminal to see which files are used by PHP in CLI mode.
Alternatively, you can run Composer with --ignore-platform-req=ext-dom to temporarily ignore these required extensions.
