The solution is: sudo docker exec -it e9438cfc3eea sh # php occ upgrade Nextcloud is in maintenance mode, no apps are loaded. Commands provided by apps are unavailable. Nextcloud is in maintenance mode Maybe an upgrade is already in process. Please check the logfile (data/nextcloud.log). If you want to re-run the upgrade procedure, remove the "maintenance mode" from config.php and call this script again. # php occ maintenance:mode --off Maintenance mode disabled # php occ upgrade No upgrade required.
