As nextcloudd has no native support for asynchronous operations, due to the use of php, this aplication is deprecated, and will not support the Nextcloud future versions (19+). There is no possibilities to implemement true support for interactive and long running occ tasks in a web terminal (for example through websockets), which can lead to serious alterations of voluminous instances.
[This issue](https://github.com/nextcloud/server/issues/16726) may give some hints on why I decided to not support this application anymore.
