As nextcloudd has no native support for asynchronous operations, due to the use of php, this aplication is deprecated, and will no longer support the Nextcloud' future versions (19+). I did not find a way to implemement true support for interactive and long running occ tasks in a web terminal whitout introducing addtional dependencies (through websockets, for example), the lack of true asynchronous occ operations can lead to serious alterations of voluminous instances.
