Getting help
In order to help you as efficiently (and quickly!) as possible, please fill in as much of the below requested information as you can.
Before clicking submit: Please check if your query is already addressed via the following resources:
- Official documentation (searchable and regularly updated)
- How to topics and FAQs
- Forum search
(Utilizing these existing resources is typically faster. It also helps reduce the load on our generous volunteers while elevating the signal to noise ratio of the forums otherwise arising from the same queries being posted repeatedly).
Some or all of the below information will be requested if it isn’t supplied; for fastest response please provide as much as you can.

Summary of the issue you are facing:
Every time I try to move a file to my external storage I get the error ““Move or copy” failed on some elements”. whenever I try to directly upload the file to the external storage via the web interface i get the error “unknown error during upload”. filesize is irrelevant, always fails. I have Automatic Ripping Machine ripping directly to the external storage drive and thats working fine
Steps to replicate it (hint: details matter!):
-
install via AIO on an ubuntu server system
-
add mounted external storage drives via external storage app
-
attempt to upload file to external drive (error)
-
upload file to main drive
-
attempt to move file to external drive (error)

Configuration
Nextcloud
The output of occ config:list system or similar is best, but, if not possible, the contents of your config.php file from /path/to/nextcloud is fine (make sure to remove any identifiable information!):

Tips for increasing the likelihood of a response
- Use the
preformatted textformatting option in the editor for all log entries and configuration output. - If screenshots are useful, feel free to include them.
- If possible, also include key error output in text form so it can be searched for.
- Try to edit log output only minimally (if at all) so that it can be ran through analyzers / formatters by those trying to help you.
we are a nextcloud forum and you’re mentioning things that have nothing to do with nextcloud…
