Hello,
my docker environment just made an update and should have pdated NC from V 27 to V 28.

It did not, but showing up this error:

using keys found in /config/keys
Initializing nextcloud 28.0.0.11 (this can take a while) …
Upgrading nextcloud from 27.1.4.1 …
Setting permissions
Setting log level to debug
Turned on maintenance mode
Updating database schema
Exception: Database error when running migration 28000Date20230906104802 for app core
Index name “lock_ttl_index” for table “oc_file_locks_org” collides with the constraint on table “oc_file_locks”.
Update failed
Maintenance mode is kept active
Resetting log level
Initializing finished

Strange enough, I cant find any results from google, github or the forum for this.

Who can advice help?

Oh wait, after some investigation, I figured out, that _org table was a copy that i once made for myself. No more need to keep it. After dropping it, the update went fine.
