Error! Could not generate a preview of this file. Please go to the next slide while we remove this imae from the slideshow.

Did you manually delete files from the file system? Looks like in your NC there are still some files linked that do not exist any more. You can run a file-scan:
sudo -u www-data php /path/to/nextcloud/occ files:scan --all

3

What deleted file system are you referring to?
I did that scanned, but error persist.

4

I thought that you perhaps manually deleted files (via SSH or FTP). There will be a feature to create and delete thumbnails manually via occ-command, not sure how far the development is:

Let’s ping @oparoz

5

That feature may be released one day, but that won’t solve the initial problem. Maybe the encryption key is corrupt. I had a similar issue with a botched upgrade (my fault).
I suspect it works with one user because the thumbnails are still there, but if you remove them, then you’ll get the same errors.

6

The original post shows that encryption is disabled…

7

I’m not using encryption.
The photos are sharing via Samba shares, if that matter.

I also tried manually add 'enable_previews' => true, in config.php
and deleted user thumbnails folder, /data/<user>/thumbnails
but error persist.

Users had experience this issue in OwnCloud prior NC.
Another thing I notice is that my MP3 Player (audios) detect all songs in the playlist when I’m log in as an admin, but as the user, it not recognize at all.

When log in as a user, the ‘music’ player built in, it says “No music found”.

https://github.com/owncloud/core/issues/16837

8

Can you temporarily disable the apps direct_menu and music?
Does it work if you place the files on your principal storage (not on external storage)? Would also be interesting if other external storage fails as well.

Could be a problem of smb as external storage, there were also reports in the owncloud forum: Size of the folder is pending - #3 by diogogomes101 - Server - ownCloud Central

9

I just tried, but error persist.
I’m using the same local storage with OC without this issue.
Same permissions setup.

10

Do you use the PHP smbclient module?
https://docs.nextcloud.com/server/9/admin_manual/configuration_files/external_storage/smb.html

@icewind can perhaps help you out with external storage problems.

11

No, I’m mounting it as local storage.
By the way, my smbclient is installed , but it says it isn’t.

Note: "smbclient" is not installed. Mounting of SMB / CIFS, SMB / CIFS using OC login is not possible. Please ask your system administrator to install it.

12

Then you don’t need smbclient. Are you using symlinks in that storage?

13

No, I’m not.
…

14

@oparoz Is this node link the reference of the file in the filecache-table?
This the the OP could try to trace which file is causing the errors…

Not sure how to debug this any further, who can help out? If you don’t get answers in a reasonable time, also consider creating a bug report on Issues · nextcloud/server · GitHub

15

Correct.

@tx7, since this problem seems to affect all the apps which need to access the filesystem, I think it would be a good idea to post the details on Github. There must be something strange going on with the Samba mount.

16

If it’s the Samba issue, then how come when I logged in as an admin, view the photos without issue.

Here’s the file permissions:

Note that the player has its own database.
and your old version has issues recognizing removed files so you could see them even if they are gone (but not play them)
By the way: in the apostore i released the neuest version of the audios-continuation calles “Audio Player”

For you issue: did you touch perhaps the mimetypes?
Did you check the filecache table if the files are still there?

18

I double check the audio player.
Don’t know about the mimetypes or filecache table.

Update: just updated to NC10, and the Photos are working fine now.

Thanks.
