即使已安装Fcitx,也无法在Ubuntu上找到Module

我正在尝试在Kubuntu 20.04上获得日语输入(fcitx-mozc)设置,这可能是一个简单的任务,但是经过数十个小时的大量教程学习后,似乎没有任何效果:

  • If I launch "Fcitx Configuration," I get a dialog saying "You're currently running KDE, but KCModule for fcitx couldn't be found, the package name of this KCModule is usually kcm-fcitx or kde-config-fcitx." kde-config-fcitx is already installed. And kcm-fcitx is not in the repo.
  • According to tutorials like this, there's supposed to be a config panel under System Settings->Regional->Input Method. No such panel exists.
  • Other tutorials have suggested installing fcitx-config-gtk3 (not in the repo) and/or fcitx-configtool (not in the repo).
  • fcitx is already selected in im-config.

我很茫然。在Mint上安装花了2秒钟,并从UI中完成了100%的安装。这是我在一两天前刚刚安装的Kubuntu新安装程序,因此,我所做的任何其他更改都不太可能影响此设置。我以某种方式缺少一些简单的东西吗?在新发布的Kubuntu 20.04上还不能用日语输入吗?
