Source: fcitx5 Dear Maintainer,
In the current packaging scheme, most people won't know that only installing `fcitx5` or `fcitx5-chinese-addons` will not make fcitx5 work. Instead, * They should install corresponding IM module `fcitx5-frontend-gtk2` `fcitx5-frontend-gtk3` `fcitx5-frontend-qt5` before they can virtually input anything. * The fcitx5 configure tool will complain about the missing`fcitx5-config-qt` but the package name is actually `kde-config-fcitx5`. * They should install `fcitx5-module-dbus` to make config work. Besides a disclaimer in /usr/share/doc/fcitx5/README.Debian , there are no other instructions to deal with the above (of many possible) packaging-related problems.
