Error al actualizar Nextcloud 21 Maintenance mode in HOST

Despu茅s de actualizar a Nextcloud 21 en mi HOST me resalto un error de instalaci贸n y al refrescar la pagina me quedo la pagina en modo mantenimiento. No me da ninguna opci贸n para volver a intentar actualizar. 驴Que puedo hacer?

After updating to Nextcloud 21 in my HOST I highlighted an installation error and when I refreshed the page, the page was left in maintenance mode. It doesn鈥檛 give me any option to try to update again. What I can do?!

As ususal, use SSH to connect to the server on the console so that you can check the Nextcloud log file content and execute occ commands zo e.g. disable the maintenance mode etc.
