Can not delete multiple files from trash bin permantly

Can not delete multiple files from trash bin permantly

Nextcloud version (eg, 18.0.2): 17.0.2
Operating system and version (eg, Ubuntu 20.04): Debian 9.12
Apache or nginx version (eg, Apache 2.4.25): 2.4.25
PHP version (eg, 7.1): 7.3.15

The issue you are facing: I cannot remove more than one file permantly.

Is this the first time you’ve seen this error? (Y/N): Yes

Steps to replicate it:

  1. Select more than one file
  2. Try to remove them.
  3. An error occurs.

If I try to remove the same items permantly one by one, it works.

To much, what can be relevant? No errors.

It’s better for performance to use redis for file-locking (the normal database can have trouble to catch up with all the activities). Not sure if the file is still locked and can’t be moved to the trashbin for that reason.

Can you delete single files? Is it always if you select several that you get this error?

Also keep in mind: 17.0.2 is not the latest release, there have been a few fixes on this branch already: https://nextcloud.com/changelog/#latest17

I have the same problem
Nextcloud 19.0.0
Docker image: nextcloud: fpm

PS: The solution for me was to execute the command:

sudo -u www-data php occ trashbin: cleanup myusername

wheremyusernameis my account name

Then the basket was completely empty
In the future, the problem is not observed.

PPS: The problem still remains
If you select all the files in the recycle bin, they are deleted
If you select multiple files, an error occurs and only the first of the selected files is deleted

‘filelocking.enabled’ => false,

in ./config/config.php solves the problem, but this is a bad solution, since the lock is disabled completely

You could try to check what process enabled the locking and doesn’t release the locking. Unfortunately, I can’t give you a guide and I don’t know if it is easy…

Is this a known issue with no fix? I have the same issue (can’t delete multiple files) on NC 22.2.2. Looking for a solution.
