When I try to upload files with web browser it's return:
Error when assembling chunks, status code 403 Forbidden

[enoch85]

Releated: #6655

Still get file locks from time to time without any reason. Just by downloading the file (I think) it get's locked which is kind of stupid.

[Floflobel]

I can download any files but I can not upload files on my nextcloud.
The table "files_lock" are empty and I tried to put "filelocking.enabled' => 'false'" into the config.php and it's does not work.

[enoch85]

@Floflobel Yes I understand that, but what I was meaning is that it gets locked when someone downloads and therefore you can't upload or download, that's what I think at least.

Strange thing is that it happens randomly, and I have no clue how to debug it.

My log is filled with "file is locked" with this file: https://cloud.techandme.se/s/whxC00V1I0l4CY8 and it's been like that forever. Just giving my input on this matter. :)

[Floflobel]

@enoch85 Ok, I understand better. I do not think it's the fact that it's downloading it locks it because I'm the only user ..
Unlike you I do not have a single file to lock but thousands.

Hoping that we will find something to debug the problem. ;)

[enoch85]

@Floflobel Feel free to debug it, if you find the cause then we can fix it. :)

Hi,
i just have the same situation here.

i cannot synchronize my files, because a file has been "locked" on the server.
I cannot even remove this file anymore on the server, my sync is broken !

What can i do to remove it ?

[enoch85]

@Wenzel Do you have any shared folders which syncs with the client? Like federated shares or similar.

[Wenzel]

@enoch85 not at all.

I tried to remove the file on the filesystem, and i'm now rescanning the filesystem with ./occ files:scan

[enoch85]

@Wenzel OK, please post the output.

[Wenzel]

Now i have new files being locked for no reasons:

Please help, we have a bug here.

[Wenzel]

And i can't delete the file:

translated: "error while trying to delete 'hypervisor_debugger.md'"

[enoch85]

@Wenzel You should always use ./occ files:scan with caution. In your case I would turn of the webserver (Apache or whatever) and then wait for 20 minutes and then remove all files locally, . When you've done that, turn on the webserver again and resync all the files.

Do it with caution though, and I'm no expert just so you know.

[Wenzel]

hello,

It happened again today

This is definitely a bug in Nextcloud server, we need to investigate.
