Currently junior-games-sim says:
Recommends: freeciv-client-gtk | freeciv-client-sdl
Please change that to
freeciv | freeciv-client
as freeciv-client-gtk is being dropped.
freeciv-client is a virtual package which will be satisifed with any freeciv
client, and freeciv itself will pull in the default (GTK3.22) client.
