Can't delete files in webinterface

i started into owncloud with a virtual-appliance-image from
after a while the users reported some issues with sharing and deleting files.

instead of find and search the problem i've set up a fresh ubuntu 16.04 and installed owncloud using mysql from scratch
everything was fine for like a week, then the same problems started

issue 1: if i delete a file in webinterface i get "Fehler beim löschen der Datei "test.txt" (roughly translated in english - error while deleting the file)

issue 2: if i want to share a folder as a link and try to enable the "allow changes" feature i get a neverending spinning circle

since the problem exists on two totally different systems i think i made a mistake in general at installation or configuration. any ideas?


please fill out the template shown when creating a new thread. Up to now even the basic info like running oC version is missing. Also have a look at your logfiles as recommended there which might give additional hints about this issue.

im sorry that i didnt post the following info before but somehow i didnt get the template when i created the thread :slight_smile:

Updated from an older ownCloud or fresh install: fresh at

Integrity status for oC9+

This doesn't look right:

Path '' is not accessible or present

But I'm not sure if this is related to your problem.

Do you know how your created this file? Upload via webinterface/oc-client? Do you use external storage? Does it happen for all files (also newly created)?
Can you also check the permissions:
sudo -u www-data ls -lisa /var/www/owncloud/data/username/files/PATH/TO/FOLDER

multiple ways.. uploading a file, create a textfile, create directory etc. everything in webinterface



here is ls -lisa output for my data directory

Any update for this issue?

I am not able to delete 3 files from my cloud.
