verbotene Zeichen am Ende von Dateien und Ordnern

erstmal bestimmte zeichen generell verbieten siehe oben config.php

danach App File Access Control installieren https://apps.nextcloud.com/apps/files_accesscontrol 

Regel für Dateiname > entspricht > /^.*\.$/i aktivieren, um Punkte am Ende einer Datei zu verhindern

Standardsprache DE für neue Benutzer 

mit

docker exec -it nextcloud-app-1 bash

in die Shell des Containers gehen (oder einfach im Volume), dann

apt-get update
apt-get install nano
nano config/config.php

und folgendes anhängen:

  'loglevel' => 2,
  'maintenance' => false,
  'default_language' => 'de',
  'default_locale' => 'de_DE',
  'default_timezone' => 'Europe/Berlin',
);

https://docs.nextcloud.com/server/16/admin_manual/configuration_server/language_configuration.html

S3 Minio als primary storage in config.php

(eigentlich über die env-vars im Stack, aber falls das verpasst wurde)

  'objectstore' =>
  array (
    'class' => '\\OC\\Files\\ObjectStore\\S3',
    'arguments' =>
    array (

      'hostname' => 'minio-s3.MEINEDOMAIN.de',
      'port' => '443',

      'key' => '3svCe...wVvluT',
      'secret' => 'mHK6Q............0GTa',
    ),
  ),

E-Mail Einstellungen SMTP in config.php (auch über GUI)

  'mail_from_address' => 'admin',
  'mail_smtpmode' => 'smtp',
  'mail_sendmailmode' => 'smtp',
  'mail_domain' => 'MEINEDOMAIN.de',
  'mail_smtphost' => 'smtp.strato.de',
  'mail_smtpauth' => 1,
  'mail_smtpport' => '587',
  'mail_smtpname' => 'admin@MEINEDOMAIN.de',
  'mail_smtppassword' => 'MEIN-123-PASSWORT',

Direkter Login (umgeht OIDC/SAML)

http://nextcloud.MEINEDOMAIN.de/login?direct=1 

Troubleshooting

Zugriff ueber eine nicht vertrauenswuerdige Domain

Zugriff über eine nicht vertrauenswürdige Domain
Bitte kontaktieren Sie Ihren Administrator. Wenn Sie Administrator sind, bearbeiten Sie die „trusted_domains“-Einstellung in config/config.php. Siehe Beispiel in config/config.sample.php.

falls die trusted domains in den env nicht passen, siehe ....
      - NEXTCLOUD_TRUSTED_DOMAINS=<nextcloud.mydomain.com>
      - OVERWRITEPROTOCOL=https
      - OVERWRITECLIURL=https://<nextcloud.mydomain.com>
...muss die config/config.php noch bearbeitet werden:

'trusted_domains' =>
  array (
   0 => 'localhost',
   1 => 'server1.example.com',
   2 => '192.168.1.50',
   3 => '[fe80::1:50]',
),

PERMISSION / OWNER FEHLER

Configuration was not read or initialized correctly, not overwriting /var/www/html/config/config.php

Passiert evtl beim Migrieren

Wenn dieser Fehler kommt, kann es sein, dass der Besitz oder die Berechtigungen der Dateien im Volume nicht stimmen.

Hier zu sehen im CLI Fileexplorer Ranger, dass der Besitzer root ist (unten links), sollte aber www-data sein.
Um den Besitzer zu ändern, eine Ebene höher gehen, sodass der Ordner _data zu sehen ist, mit ! ein Shell Command ausführen
('@'-Zeichen ist der Shortcut für Shell-Kommando in Ranger):

chown -R www-data:www-data _data

das ändert die Rechte rekursiv, also auch alle untergeordneten Dateien und Ordner:

WICHTIG! Die Environment-Variablen NEXTCLOUD_TRUSTED_DOMAINS, OVERWRITEPROTOCOL und OVERWRITECLIURL werden in die config.php von Nextcloud nur bei Erstellung des Containers geschrieben. Eine nachträgliche Änderung ist nicht möglich (zumindest nicht ueber docker-compose ENVs. Wenn man es aendern möchte muss man die config.php im container editieren).
