Hello! I’m having trouble updating NextCloud. When I start the update, an error appears: The following extra files have been found: cloud_files.
This is the directory where all files uploaded to the cloud are stored. How to solve this problem?
Thank you very much and sorry for my English!

Only one error in the log:
[PHP] Error: Invalid argument supplied for foreach() at /apps/serverinfo/lib/OperatingSystems/DefaultOs.php#120
GET /index.php/settings/admin/serverinfo

Are you sure there is no file with the name cloud_files laying around?


Yes! Here is a screenshot of the site directory.
There is only a cloud_files directory but all user files are stored in it
