Dies sollte manuell funktionieren, ansonsten dient das nachfolgende Nextcloud Skript dazu:

#!/bin/bash
nextcloudpath='/webserver/cloud'
webuser='www-data'
webgroup='www-data'
rootuser='root'
 
printf "Creating possible missing Directories\n"
mkdir -p $nextcloudpath/data
mkdir -p $nextcloudpath/assets
mkdir -p $nextcloudpath/updater
 
printf "chmod Files and Directories\n"
find ${nextcloudpath}/ -type f -print0 | xargs -0 chmod 0640
find ${nextcloudpath}/ -type d -print0 | xargs -0 chmod 0750
 
printf "chown Directories\n"
chown -R ${rootuser}:${webgroup} ${nextcloudpath}
