It looks like something is wrong with your WebDAV connection (which the sync client uses)
Can you check the permissions of your config and data folder ?

[nickdjones]

The config and data folders haven't been touched (did the wipe and extract upgrade method) and were working with Owncloud 6.0.0a. /config/ is apache:apache 777 and /data/ is apache:apache 770.

[PVince81]

The issue you're having is that the webdav interface is returning a HTML error page instead of the requested URL, which causes the issues you see. I thought the error in question could be about permissions.

Please try the following command:

curl --max-redirs 0 http://localhost/owncloud/remote.php/webdav/ >>test1.html 

Replace localhost/owncloud to your owncloud's path.

test1.html should contain the error message.

We need to look into how to propagate the error message correctly in the future.

Similar to #6119

[nickdjones]

Never mind it was the apps directory permissions. Sorry.

[DeepDiver1975]

The question is if we can support this case better.

In case there is an issue with the overall owncloud setup - like permissions on config, app, data or database offline
we should return a proper dav response with valid xml and a correct http status code.

The only way to accomplish this from my point of view is to change the way base.php is working:
instead of rendering an html error page we shall throw a proper exception which we can convert to the proper error response:

• create a dav xml error response
• display a thml error page
• render a json error message

@PVince81 objections?

[PVince81]

Yes, makes sense.
Let's use #6119 which is still open.
