Contao lässt sich nicht installieren

**patweb** · 08.07.2022, 06:08

Guten Morgen,

ich habe Contao mit dem Contao Manager schon sehr oft installiert - aber seit kurzem will es mir einfach nicht mehr gelingen und ich habe keine Ahnung, weshalb. Auf dem Webspace liegen mehrere Contao-Installationen, die ohne Probleme laufen. Ob ich dort Updates etc. durchführen kann, habe ich lieber noch nicht probiert.

Ich hoffe sehr, dass folgender Auszug aus den Logs euch eine Idee gibt, woran es liegen könnte und bin für jeden Tipp dankbar. Den Manager habe ich mir gefühlt 10x heruntergeladen und ich habe die Installation sowohl mit PHP 7.4 als auch PHP 8.0 versucht - immer ohne Erfolg.

Code:

$ /usr/iports/php74/bin/php -q -dmax_execution_time=0 -dmemory_limit=-1 -dallow_url_fopen=1 -ddisable_functions= -ddate.timezone=Europe/Berlin /usr/local/www/apache24/noexec/xxxx/public/contao-manager.phar.php composer install --no-dev --no-progress --no-ansi --no-interaction --optimize-autoloader

contao-components/installer contains a Composer plugin which is blocked by your allow-plugins config. You may add it to the list if you consider it safe. See https://getcomposer.org/allow-plugins
You can run "composer config --no-plugins allow-plugins.contao-components/installer [true|false]" to enable it (true) or keep it disabled and suppress this warning (false)

Hallo Patrick,

bei welchem Hostingprovider bist du denn?

Ist das wirklich eine Neuinstallation?
Ich frage wegen

Code:

Nothing to install, update or remove

**patweb** · 08.07.2022, 09:21

Der Provider ist Hostnet: https://www.hostnet.de/
Wir haben dort mehrere Contao-Installationen auf dem gleichen Server laufen und nie Probleme gehabt, so dass es dort *grundsätzlich* funktionieren sollte. Aber man weiß ja nie.

@mlweb
Ja, es ist eine Neuinstallation. Allerdings war das Log oben das, das bei der "automatischen Reparatur" kommt, nachdem die initiale Installation fehlschlägt. Ich habe die Installation nochmal ganz neu gestartet:
