Помог вот этот способ.
Manually disable locking state:
- put Nextcloud in maintenance mode: edit
config/config.phpand change this line:
'maintenance' => true, - Empty table
oc_file_locks: Use tools such as phpmyadmin or connect directly to your database and run (the default table prefix isoc_, this prefix can be different or even empty):
DELETE FROM oc_file_locks WHERE 1 - disable maintenance mode (undo first step).
- Make sure your cron-jobs run properly (you admin page tells you when cron ran the last time): https://docs.nextcloud.org/server/13/admin_manual/configuration_server/background_jobs_configuration.html
