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. 
The Basics
-
Nextcloud Server version (e.g., 29.x.x):
- 32.0.5.0
-
Operating system and version (e.g., Ubuntu 24.04):
- Linux (Debian-based host)
-
Web server and version (e.g, Apache 2.4.25):
- nginx (reverse proxy)
-
Reverse proxy and version _(e.g. nginx 1.27.2)
- nginx/1.26.3
-
PHP version (e.g, 8.3):
- PHP 8.3 (php:8.3-fpm)
-
Is this the first time you’ve seen this error? (Yes / No):
- Yes
-
When did this problem seem to first start?
- During upgrade to Nextcloud 32.0.5.0 using the Web Updater and commandline
-
Installation method (e.g. AlO, NCP, Bare Metal/Archive, etc.)
- Custom Docker installation (manual compose + php-fpm container)
-
Are you using CloudfIare, mod_security, or similar? (Yes / No)
- No
Summary of the issue you are facing:
The Nextcloud Web Updater fails during the backup creation step with:
Create backup failed
Could not copy "/cloud/apps/weather_status/img/met.no.icons/cloudy.svg"
to "/mnt/cloud-data/updater-ocXXXX/backups/nextcloud-32.0.5.0-XXXXXXXX//apps/weather_status/img/met.no.icons"
The destination path is a directory, not a file path.
This causes PHP copy() to fail.
This issue is not specific to the weather_status app.
It is simply the first app where the failure occurs.
If that app is removed or disabled, the updater fails later on other apps with similar directory structures.
Steps to replicate it (hint: details matter!):
- Run Nextcloud 32.0.5.0
- Use a Docker installation with:
-
/cloudmounted for application files -
/mnt/cloud-datamounted as data directory
-
- Ensure multiple apps are installed (default apps are sufficient)
- Run upgrade via Web Updater
- Backup step fails during copy of an app asset file
Log entries
Nextcloud
Please provide the log entries from your Nextcloud log that are generated during the time of problem (via the Copy raw option from Administration settings->Logging screen or from your nextcloud.log located in your data directory). Feel free to use a pastebin/gist service if necessary.
Create backup failed
Could not copy "/cloud/apps/weather_status/img/met.no.icons/cloudy.svg"
to "/mnt/cloud-data/updater-ocXXXX/backups/nextcloud-32.0.5.0-XXXXXXXX//apps/weather_status/img/met.no.icons"
Web Browser
If the problem is related to the Web interface, open your browser inspector Console and Network tabs while refreshing (reloading) and reproducing the problem. Provide any relevant output/errors here that appear.
No client-side error. Failure occurs server-side.
Web server / Reverse Proxy
The output of your Apache/nginx/system log in /var/log/____:
No relevant nginx errors.
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!):
Key points:
-
datadirectory =
/mnt/cloud-data -
Nextcloud root =
/cloud -
PHP-FPM running as
www-data(UID/GID 33) -
Permissions verified OK (read/write on both directories)

Apps
The failure occurs when copying files from directories such as:
/cloud/apps/*/img/*/
Example:
/cloud/apps/weather_status/img/met.no.icons/
But the same issue appears with other apps once the first failing app is removed or disabled.

Additional debugging already performed
-
Source file exists and is readable
-
Destination directory exists and is writable
-
PHP process runs as UID 33 (www-data)
-
Manual PHP test:
Works:
copy("cloudy.svg", "/path/met.no.icons/cloudy.svg")
Fails:
copy("cloudy.svg", "/path/met.no.icons")
This matches exactly the updater failure.
Workaround
Disabling and deleting the failing app allows the updater to continue, but then it fails on another app later.
Upgrade continues but then fails on another app with similar structure.
Expected behaviour
Updater should copy files with correct destination path including filename, even when destination directory exists.
Conclusion
The updater backup routine appears to pass a directory path instead of a file path to PHP copy().
This causes failures when backing up files located inside nested directories in app assets.
The issue affects multiple apps and is not limited to a single one.
