> Did you edit /etc/radicale/config and /etc/default/radicale? Yes. I enabled in the defaults (though in my experience with other packages since moving to jessie, systemd tends to ignore /etc/defaults in many of them). I am fairly certain this is a regression in my setup and that it used to start fine.
> Did you suppress some package recommendations on your system? Possibly. Which would you suggest trying to install in this case?
