I am using Evolution on arch and I am running Nextcloud 12 (No warnings) on ubuntu 16.04. I can add the Cal/task/Contacts CalDAV but ass soon as I try to create something it gives this warning:
Failed to create a task in the task list “CalDAV : Nextcloud”
Cannot create calendar object: Failed to put data: HTTP error code 403 (Forbidden): Sabre\DAV\Exception\Forbidden
Permission denied to create file (filename dbd67a692f6b124362ff383ce1dfddd4469253e7.ics)[exception][message]
And a password promt /(when I add the link it also asks for password, but accepts)
Any ideas?
