*ATTENTION:* Do not post your config.php file in public as is. Please use one of the above
methods whenever possible. Both, the generated reports from the web-ui and from occ config:list
consistently remove sensitive data. You still may want to review the report before sending.
If done manually then it is critical for your own privacy to dilligently
remove *all* host names, passwords, usernames, salts and other credentials before posting.
You should assume that attackers find such information and will use them against your systems.

List of activated apps:

If you have access to your command line run e.g.:
sudo -u www-data php occ app:list
from within your ownCloud installation folder.

Are you using external storage, if yes which one: local/smb/sftp/…

Are you using encryption: yes/no

Are you using an external user-backend, if yes which one: LDAP/ActiveDirectory/Webdav/…

LDAP configuration (delete this part if not used)

With access to your command line run e.g.:
sudo -u www-data php occ ldap:show-config
from within your ownCloud installation folder

Without access to your command line download the data/owncloud.db to your local
computer or access your SQL server remotely and run the select query:
SELECT * FROM `oc_appconfig` WHERE `appid` = 'user_ldap';

Eventually replace sensitive data as the name/IP-address of your LDAP server or groups.

It looks to me that there are quite a lot too much files in your installation. I would try to fix those messages first by following the mentioned documentation and try again.

If that doesn’t solve your issue then i think its probably the best to report the initial issue to the issue tracker of that app.

Hi Tom.

I assume you refer to the integrity scan right?
How can I determine which files I can delete?
Can all files marked as “Extra_files” be deleted?
Are those files from previous owncloud versions?


Ah, yes. I was referring to the integrity messages which i think is showing that the upgrade wasn’t done correctly according to the documentation causing old files left on the installation.

When i got such message i had followed the mentioned documentation:

which explains that you should delete all EXTRA_FILES to solve the integrity message.

Hi Tom

I tried but after solving the integrity issues it still does not work.



then i think this here would be the way to go:
