Nextcloud externer Speicherplatz (Problem beim Herunterladen)

Florian_N · May 9, 2023, 3:02pm

Hallo leider habe ich beim Hochladen keine Probleme mit Nextcloud externer Speicher, aber wenn etwas heruntergeladen wird erhalte ich diese Fehlermeldung:

C****** Cloud

Interner Serverfehler

Der Server konnte die Anfrage nicht fertig stellen.

Sollte dies erneut auftreten, senden Sie bitte die nachfolgenden technischen Einzelheiten an Ihren Server-Administrator.

Ist die serverseitige Verschlüsselung aktiviert?

Sonst mit dem Fehler gibt es hier noch einen Bugreport:

Error while backing up to external app data via SFTP

opened 03:09PM - 14 Apr 22 UTC

### Expected Behavior Get a completed full backup over SFTP connection to exter…nal storage. ### Current Behavior Backup fails after backing up random number of chunks. ### Failure Information (for bugs) Steps to Reproduce Install Nextcloud Hub II 23.0.3. Install external storage and configure it with SFTP connection using username and password. Install backup app 1.0.6 and set backups and temporary data to go to external storage. Try to create a full backup. ### Context Please provide any relevant information about your setup. This is important in case the issue is not reproducible except for under certain conditions. Nextcloud Hub II version: 23.0.3 Backup app version: 1.0.6 Nextcloud is installed on Ubuntu 20.04 LTS I have configured app data to be on external storage configured with SFTP. I can access the external storage with files. Every time i run "sudo -u www-data php /var/www/nextcloud/occ backup:point:create" it will backup and create chunks on external storage. I have a lot of data that is backed up so it takes several hours for a full backup. But after a couple of hours it fails with message: In ChunkService.php line 597: Chunk data-8fe30df3-c083-4b2a-90ce-6878c0de32fe.zip not valid ### Backup Output: ``` > maintenance mode: on >

Evtl. direkt in die Logfiles reinschauen, da gibt es vielleicht noch etwas mehr als dein Screenshot. Steht halt dort nur dabei dass es nicht geklappt hat, aber nicht warum. Ggf. Webserver Zugriff und Error-Logs anschauen, genau zu dem Zeitpunkt, wo du auch die anderen Meldungen hast.

Ich würde noch direkt auf der Konsole mit scp versuchen, von dem SFTP-Server was runterzuladen. Nur falls dir da eine Firewall reinfunkt o.ä.

Falls deine NC Version aktuell ist, und wir sonst keine Hinweise finden, würde es Richtung Bug-Report gehen.

Serverseitige Verschlüsslung ist aktiviert.

Im Bugtracker gibt es ein paar Bugs mit SFTP, schau dir die mal in Ruhe durch. Auf den ersten Blick habe ich nichts gesehen, was genau die gleichen Fehler macht wie bei dir.

Falls du nichts passendes findest, würde ich dort einen neuen Report aufmachen.

Florian_N · May 13, 2023, 6:07am

Das Teilen von Dateien im External Storage funktioniert nicht

tflidd · May 13, 2023, 5:47pm

Wenn du schon nicht darauf zugreifen kannst, hast du ja schon dort prinzipiell ein Problem. Mit shares ist dann ein anderes Thema, ist dann ggf. ein anderer Bug.

Florian_N · June 8, 2023, 10:14am

Funktioniert aber ohne Verschlüsselung
