I use two nextcloud updated to version 18.0.1 and I have problem in deleting files from a shared federated folder. while nextcloud user who shared my folder with me you can safely operate the files I who received the federated folder I can upload the images but not delete them although on another instance I have permissions on the folder for editing. I get this error "OC \ User \ NoUserException: Backends provided no user object" how can I solve?

Attach complete error:

    in practice, those who receive the federated folder from another nextcloud despite having the permissions to delete, cannot delete files that only the one who shared the federated folder puts in that folder, while I, who received the shared folder in my nextcloud, can only files but don't delete them as well if other has given me the permissions.

    @nickvergessen I read that you committed to the problem that I have on nextcloud 12,

    nextcloud/files_downloadactivity#8

    but now I run on instance nextcloud 18.0.1 and I still have that error on the federated shared folders where those who shared can delete the files and those who receive the federated folder it cannot delete the files inside despite having received the permissions. how to solve?

    I jus had a look at the stacktrace from #19647 (comment) and the code. The problem seems to be this in the trashbin app (OCA\Files_Trashbin\Storage::shouldMoveToTrash):

    // check if there is a app which want to disable the trash bin for this file
$fileId = $this->storage->getCache()->getId($path);
$owner = $this->storage->getOwner($path);
if ($owner === false) {
	$nodes = $this->rootFolder->getById($fileId);
} else {
	$nodes = $this->rootFolder->getUserFolder($owner)->getById($fileId);
}

    This assumes $owner is either false or a user. However, for federated shares, $owner is something like [email protected]/, which is neither false nor a user. As a result, $this->rootFolder->getUserFolder($owner) raises an exception and the delete operation fails.

    The problem seems to have been introduced in this commit: 8e7c287. I think the trashbin behavior needs to be adjusted to work with federated shares. Unfortunately, I don't know enough about nextcloud internals to know how the trashbin should be correctly handled in this case.

    @rullzer Can you help?

    Fwiw: I can reproduce this issue on 19.0.1 and when it occurs I can also reproduce this other issue: nextcloud/desktop#853 regarding high CPU usage of the desktop client. This high CPU usage occurs precisely after I receive a federated share and then try to delete a file in this share (which fails as described above). If I remove the federated share, also the desktop client syncing issue is gone. The reason seems to be that the server always sends a new Etag to the client for the federated share so that the client is constantly syncing (according to logs recorded with nextcloud --logdebug). I will write a more detailed comment about this when I find the time.

    I also got this problem since a a long time. Now, with 19.0.3 it's still appearing in my log at every run of cron.

    I am experiencing the same problem on 19.0.3. Remote user shared a folder with me. They have given me full permissions to create, edit, and delete. I am able to do all of but the latter. The logs show the following stack trace:

    I have the same problem. Since in #19647 (comment) it was mentioned that files_trashbin could be the problem, I disabled the "Deleted Files" app on the receiving cloud (it's still enabled on the sharing server). I could then delete the shared folder without a problem.

    I am confused why this is a duplicate of nextcloud/groupfolders#2559, when this one is over 2 years older than the linked issue. This issue also contains more information about the problem and tested configurations. It was closed in the meantime but reopened. It seems there is some confusion around here.

    No there isn't. Problem is that people see "Backends provided no user object" in the error log and thinks "this is the same issue" while it is not the same issue. All recents reports (this year reports) on this issue are related to GroupFolders app, not Server.

    So, it is a duplicate since the issue must be tracked on GroupFolders repo, not here.

    I don't think this is the case, as we don't have the GroupFolders app installed. It only happens with public shares in our instance, see my comment (#19647 (comment)) above.

    I agree. I don't have that app either and I get the same error.

    Because "Me too I have the same problem/error/wathever..." means nothing unfortunately...

    I get this error accessing a public share with read&write permissions enabled. I'm accessing that folder via curl and rclone and using the share's id as well as a password to upload and edit files in that folder.

    Good.

    #41786 has been shipped with v27.1.5 (or v28), released today, it can help in this case.

    Can you test and report back?
    If this does not help, please provide a JSON backtrace.

    @Marcus1Pierce your error is a duplicate of nextcloud/groupfolders#2559

    Keep it simple:

    1. if the line /groupfolders/lib/Versions/VersionsBackend.php is present in the backtrace, it is a duplicate of Backends provided no user object / Duplicate entry for key 'gf_versions_uniq_index' groupfolders#2559 in this case please also make sure you're using Group Folders app version v16.0.1. If these 2 conditions are met (line is present and app is v16.0.1) report on groupfolders repo.
    2. if the line is not in the logs, and you are using 28 or 27.1.5, report a new issue here. If line is not present and you're using v26 or v27.1.4 or less, upgrade to v27.1.5.

    @solracsf Sorry i though it the same think. I didn't read your comment before.

    1. if the line /groupfolders/lib/Versions/VersionsBackend.php is present in the backtrace, it is a duplicate of Logs filled with cron errors "Backends provided no user object" groupfolders#2559 in this case please also make sure you're using Group Folders app version v16.0.1. If these 2 conditions are met (line is present and app is v16.0.1) report on groupfolders repo.
    2. if the line is not in the logs, and you are using 28 or 27.1.5, report a new issue here. If line is not present and you're using v26 or v27.1.4 or less, upgrade to v27.1.5.

    If i check groupfolders v16.0.1 is available in Nextcloud v28. I think i can't upgarde to Nextcloud 28 for now. And for Nextcloud v27.1.5, latest version of groupfolders is 15.3.1.
