Cannot upload files to ownCloud server

Hello!

I am having trouble syncing my Linux desktop client with the server. Could you please review the below and let me know if there is a way to get ownCloud to work?

Thanks!

Expected behaviour

The file should be uploaded to the server after being copied into the ownCloud desktop folder.

Actual behaviour

I receive an error message saying that "The item is not synced because of a previous error. Server: Forbidden"

Steps to reproduce

  1. Copy file into ownCloud desktop folder
  2. Wait for error message to arrive

Check your apache user (either "www-data" or "apache") can access to the ownCloud server base directory.

If you want to start from scratch, follow the official documentation (and report anything that might need clarification): https://doc.owncloud.org/server/10.0/admin_manual/installation/
