Chmod(): Operation not permitted at /var/www/nextcloud/apps/recognize/lib/Migration/InstallDeps.php#169

Hi all,

I see with every update the following line in my log:

chmod(): Operation not permitted at /var/www/nextcloud/apps/recognize/lib/Migration/InstallDeps.php#169

I already checked all the file permissions and they are correct (www-data user is owner of everything) and I use the system node installation:

(The wheel never stops spinning, so there may be something wrong also)

I assume this is related to node dependencies, but how can I solve this?

kind regards
