Hi nextcloud users,
My Sync of Calendar and Contacts is not working anymore => contacts and calendar is not synced.
DavDroid/DAVx gives HTTP 500 error.
Nextcloud gives a very long FATAL ERROR “Doctrine\DBAL\Exception\UniqueConstraintViolationException: An exception occurred while executing 'INSERT INTO
Verursacht vonDoctrine\DBAL\Driver\PDOException: SQLSTATE: Integrity constraint violation: 1062 Duplicate entry ‘0’ for key ‘PRIMARY’
What has changed:
I just upgraded from NC 15 to NC 17 (over NC 16).
I had issues in NC 15 with file locking and disabled file locking + deleted all entries in mysql “file_lock” and “filecache” (recommendations in this forum). After that I did occ commands to repair filesystem and filecache. After login to NC 15 worked again I enabled file locking again and updated NC. In NC 17 all files are there. Only Sync is not working.
One thing got my eye: In “oc_cards” all the “uri” have a domain ending “@ssl-account.com” that was an old way to use https at my webhost. The url is not in use anymore. I think it has to do with well-known uri. Maybe this has some impact?
Any ideas how to solve this?
Thanks in advance.
edit: if I disable Activity App sync works again. But the app and NC17 is completely new. Any ideas?
