Unable to delete a file/folder after switching to NC 30.0.4 and Group Folder 18.0.8 ("Delete file" action failed)

[supr4s]

Hi everyone,

Since upgrading to Nextcloud 30.0.4 and switching to Group Folder 18.0.8, it is no longer possible to delete a folder/file.

This issue will be linked to this one: #2604 => having had no feedback, I tested by updating everything and the initial problem disappeared, but now you can't no longer delete a folder/file.

Steps to reproduce

1. Create group folders A & B
2. Both group folders are only set has admin group and no advanced permissions
3. Inside of each folders create a folder ( x inside of A and y inside of B )
4. Share folder x to group G_x and share folder y to group G_y
5. Now set group G_x and G_y to a user
6. Connect to the user and try to delete a file/folder: permission denied. Create, edit, move => OK but not delete

Expected behaviour

A user with editing rights must be able to make the deletion.

Actual behaviour

From GUI :

"Delete file" action failed

From Nextcloud logs :

Not an isolated case, I have the same thing on a second server (same configuration).

Temporary fix: delete/disable the trash app (Deleted files). Now I don't have any problems!

[Jormodn]

I can confirm the bug and the Workaround

[schengawegga]

I have the same problem.
Disabling the "Deleted files" app will fix this error temporarily, but it is not a good option for my business.
After creating the folder "/demo02/files_trashbin/groupfolders/5" on the filesystem manually, the file can be deleted now, but it will NOT be shown in the users or in the groupfolders trash bin at all.
The file was moved correctly in that filesystem folder, but a recovery of that file will be impossible.

Also the deletion will not be shown in the users activities, but in the groupadmins activities without the filename and a file not found icon.

[supr4s]

Yes indeed, it's only a temporary fix, I also need the trashbin but there's no alternative for the moment ..
@joshtrichards perhaps you could pass this to the development teams ?

[Kryptopirat]

I can also confirm the error and the workaround.

[Nordlead75]

i have the same error

[Longjogger]

This error is very annoying and the workaround is in most settings no option. When is the fix expected?

[EGVuser]

i have the same error

[DocSnyderLiMA]

Same Problem here...

Same Problem, But Found a Solution That Worked for Me

I also had the same issue. I found a solution that worked in my case since I share subfolders, not the root group folder.

1. I created account groups and added users to each group.
2. Then, in the group folder settings, I added the group on both sides (group or team, advanced permissions) without granting any permissions.
3. Next, I went to the files section, found the root folder, and in the sharing options, I selected the group that should have access to it and only granted write permissions. (bottom section)
4. For the subfolders that the group needed access to, I granted the respective permissions (at the top).
5. If there was an additional subfolder under the root that the group wasn’t authorized to access, I went to that folder, selected "share," and in the bottom section, I denied permissions for that group.

That’s it!

What I’ve noticed is that the trash bin is tied to the root group folder. Since users only have write permissions for the subfolders, this causes an error when deleting files. My suggestion to the development team would be:

• Create trash bins for the subfolders themselves.

• Alternatively, if keeping the current approach, ensure that when write permissions are granted to a subfolder, users are also granted write access to the root trash bin where deleted items are stored.

I hope this helps others. So far, it’s working for me.

Best regards!
