Fatal error: Uncaught exception RuntimeException with message The HOME or COMPOSER

Contao 3.5.27

Meine Paketverwaltung schmeißt in mehreren Installationen Fehlermeldungen raus. Diesen Part habe ich, weil vorher ein SSL Fehler angezeigt wurde, schon geändert, das hilft leider nicht:

"type": "composer",
"url": "https://legacy-packages-via.contao-community-alliance.org/"

Aktuelle Fehlermeldung:

Code:

Fatal error: Uncaught exception RuntimeException with message The HOME or COMPOSER_HOME environment variable must be set for composer to run correctly thrown in phar://composer/composer.phar/src/Composer/Factory.php on line 641 #0 phar://composer/composer.phar/src/Composer/Factory.php(69): Composer\Factory::getUserDir() #1 phar://composer/composer.phar/src/Composer/Factory.php(160): Composer\Factory::getHomeDir() #2 phar://composer/composer.phar/src/Composer/Factory.php(300): Composer\Factory::createConfig(Object(Composer\IO\BufferIO), '/usr/local/www/...') #3 [internal function]: Composer\Factory->createComposer(Object(Composer\IO\BufferIO)) #4 phar://composer/composer.phar/src/Composer/Util/Silencer.php(68): call_user_func_array(Array, Array) #5 system/modules/!composer/src/Runtime.php(585): Composer\Util\Silencer::call(Array, Object(Composer\IO\BufferIO)) #6 system/modules/!composer/src/ClientBackend.php(300): ContaoCommunityAlliance\Contao\Composer\Runtime::createComposer(Object(Composer\IO\BufferIO)) #7 system/modules/!composer/src/ClientBackend.php(125): ContaoCommunityAlliance\Contao\Composer\ClientBackend->loadComposer() #8 system/modules/core/classes/Backend.php(423): ContaoCommunityAlliance\Contao\Composer\ClientBackend->generate() #9 system/modules/core/controllers/BackendMain.php(131): Contao\Backend->getBackendModule('composer') #10 contao/main.php(20): Contao\BackendMain->run() #11 {main}

Wäre das hier der richtige Ansatz für mich? https://community.contao.org/de/show...-)-GEL%C3%96ST
