Dear Maintainer, I'm preparing a buster server, I received it without anything graphical. After entering the server with ssh -XC and installing geany with sudo apt install geany I get: $ geany Unable to init server: Could not connect: Connessione rifiutata Geany: cannot open display And actually geany has installed no graphical stuff. On the contrary, if I install nautilus, it installs all the packages needed to run a graphical app.
