Anleitung - Installation Ubuntu 20.04 VPS - Shopware 6 - Apache2

Hallo Forum.

die Antwort von @SCOOPEX hat der Problemlösung nichts beigetragen.

Jetzt gibt es mit einem Internetbrowseraufruf folgenden Hinweis:

Fatal error : Uncaught LogicException: Extension DOM is required. in /var/www/html/vendor/symfony/config/Util/XmlUtils.php:50 Stack trace: #0 /var/www/html/vendor/symfony/config/Util/XmlUtils.php(146): Symfony\Component\Config\Util\XmlUtils::parse() #1 /var/www/html/vendor/symfony/dependency-injection/Loader/XmlFileLoader.php(405): Symfony\Component\Config\Util\XmlUtils::loadFile() #2 /var/www/html/vendor/symfony/dependency-injection/Loader/XmlFileLoader.php(50): Symfony\Component\DependencyInjection\Loader\XmlFileLoader->parseFileToDOM() #3 /var/www/html/vendor/shopware/core/Framework/Framework.php(59): Symfony\Component\DependencyInjection\Loader\XmlFileLoader->load() #4 /var/www/html/vendor/symfony/http-kernel/Kernel.php(678): Shopware\Core\Framework\Framework->build() #5 /var/www/html/vendor/symfony/http-kernel/Kernel.php(649): Symfony\Component\HttpKernel\Kernel->prepareContainer() #6 /var/www/html/vendor/symfony/http-kernel/Kernel.php(547): Symfony\Component\HttpKernel\Kernel->buildContainer() #7 /var/www/html/vendor/shopware/core/Kernel.php(194): Symfony\Component\HttpKernel\Kernel->initializeContainer() #8 /var/www/html/vendor/shopware/recovery/Install/src/app.php(45): Shopware\Core\Kernel->boot() #9 /var/www/html/vendor/shopware/recovery/Install/index.php(74): getApplication() #10 /var/www/html/public/recovery/install/index.php(6): require_once(‚…‘) #11 {main} thrown in /var/www/html/vendor/symfony/config/Util/XmlUtils.php on line 50

Ist PHP 8.0.16 und MariaDB-1:10.7.3 mit Shopware 6.4.8.1 compatibel?

Meine /etc/apache2/sites-available/000-default.conf

<VirtualHost *:80>
        # The ServerName directive sets the request scheme, hostname and port that
        # the server uses to identify itself. This is used when creating
        # redirection URLs. In the context of virtual hosts, the ServerName
        # specifies what hostname must appear in the request's Host: header to
        # match this virtual host. For the default virtual host (this file) this
        # value is not decisive as it is used as a last resort host regardless.
        # However, you must set it for any further virtual host explicitly.
        #ServerName www.example.com

        ServerAdmin webmaster@localhost
        DocumentRoot /var/www/html

        # Available loglevels: trace8, ..., trace1, debug, info, notice, warn,
        # error, crit, alert, emerg.
        # It is also possible to configure the loglevel for particular
        # modules, e.g.
        #LogLevel info ssl:warn

        ErrorLog ${APACHE_LOG_DIR}/error.log
        CustomLog ${APACHE_LOG_DIR}/access.log combined

        # For most configuration files from conf-available/, which are
        # enabled or disabled at a global level, it is possible to
        # include a line for only one particular virtual host. For example the
        # following line enables the CGI configuration for this host only
        # after it has been globally disabled with "a2disconf".
        #Include conf-available/serve-cgi-bin.conf
</VirtualHost>

# vim: syntax=apache ts=4 sw=4 sts=4 sr noet

Wo finde ich eine funktionierende Anleitung, wie löse ich das Problem?
