Thank you very much for your replies.
As it seems I misunderstood something here.
I thought that I can use the Marvin app to sync my books over wifi so to use the calibre server.

But as you say you have to connect the iPad to the computer. But I think there is no kernel module for Apple devices on Linux.

Otherwise I can just upload those books on my owncloud account and the import them into iBooks or Marvin.

But would you recommend the Marvin reader. Is it better than iBooks?

I will drop an email to the developer of Marvin maybe he can add this functionality.


So now I think I know how this works. You have to choose OPTS not calibre. There you can search for calibre server over wifi.
Little bit confusing for first time users.
I will try it when I am at home.
