Nextcloud, install non aboutie

Bonsoir,
Mille excuse j’utilise Ctrl + Maj + 9 ci dessous, c’est bon ?
Voila comment j’ai procédé :
Installation de YNH sur le raspi (dernière version), mises à jour et transfert sur un ssd externe
Une première installation de nextcloud a planté, une deuxième aussi.
Sur tes conseils j’ai supprimé le dossier /home/nextcloud retenté une installation. Toujours le même log d’erreur :
