Apache dockered system, with server-side encryption. Every time a file is uploaded it causes this title error.

Nextcloud 21.0.2 - docker (apache version 21)

Staff, server-side encryption enabled, I send a file to nextcloud and keep giving this error:

These are different errors, the other one has already been fixed, this is another error, it's when sending a file.

I think they're not paying attention to this error, or they don't care about encryption.

@AndyXheli I am no longer using the encryption app (I disabled it) and I do no longer support any code I wrote for that app.

Yeah just noticed I have these error as well, only on an external storage, just a local folder with encryption disabled on this folder.

And I do have the patch from #21578 applied on my instance.
So it seems it's a different issue.

The same thing is happening to me while using encryption with an Amazon S3 external storage on NextCloud version 22.1.1.

edit: I'm also running inside of docker

Still receiving these errors with Nextcloud 22.2.3, External Storage connected to the local filesystem. In my case, the error is only triggered with WebDAV access.

Using 23.0.3
This also shows a popup with "Error deleting file" when a user tries to delete a file from the browser. It actually deletes the file but the user need to refresh the folder on the web ui to see the file is gone.
The file which is accessed is an external storage mapped to local.

Using 23.0.3 This also shows a popup with "Error deleting file" when a user tries to delete a file from the browser. It actually deletes the file but the user need to refresh the folder on the web ui to see the file is gone. The file which is accessed is an external storage mapped to local.

Stacktrace as json format (click me)

Same for me. Happens only on SMB folders when deleting files. Exact same behavior on 23.0.4

Encryption is disabled btw.

Same here on SFTP/Webdav, let me know if additional logging / testing is needed. Would like to help solve this asap!

It seems I'm able to copy/move files from anywhere and they get properly encrypted on both Webdav and SFTP (File content encrypted upon opening not via NC) but when trying to recursively move or copy a folder (either by dragging or selecting move/copy) it results in unable to copy / move FOLDER.

Please advise.

ps, it seems file/folder names are still intact only the content is encrypted, could anyone confirm this is supposed be? I recall it does, just want to be sure.

I believe this is fixed (at least in >=NC26) via #34724. Is anyone on this thread that has moved to at least NC26 still experiencing this behavior?

@joshtrichards I've been following this issue because I had the same problem and can confirm that this no longer happens with WebDAV (NC27.0.2).

[PHP] Fout: Trying to access array offset on value of type bool at /var/www/nextcloud/lib/private/Files/Storage/Wrapper/Encryption.php#453

Not sure the underlying cause, but did a little digging today. Leaving a few notes here for next time:

server/lib/private/Files/Storage/Wrapper/Encryption.php

Lines 447 to 453 in cde21ff

$info = $this->getCache()->get($path);
// only get encryption module if we found one in the header
// or if file should be encrypted according to the file cache
if (!empty($encryptionModuleId)) {
$encryptionModule = $this->encryptionManager->getEncryptionModule($encryptionModuleId);
$shouldEncrypt = true;
} elseif (empty($encryptionModuleId) && $info['encrypted'] === true) {

$info above (line 453) can end up being set to false rather than being an array due to the get() returning false if the file/folder can't be found in the cache. And there's currently no check for that state before trying to access the $info array to see if the file's encrypted flag (which will only be set if the cache entry exists) is set to true.

Questions to follow-up on:

  • Why are they not found in the cache?
  • Are we perhaps checking the header and setting the $encryptionModuleId before we confirm the file exists? [my initial look showed this as a possibility, but this is a complicated area of code so I'm not ready so say that's what's happening here]

Triggering this code path should only be possible in environments where there are no headers on the encrypted files (old installations only I believe)... though if we're setting $encryptionModuleId in some cases at the wrong time (i.e. before checking file existence) then we might also be triggering this code path under unplanned circumstances.
