I’m trying to enable Japanese input on Fedora 42 KDE using this guide: Japanese Text Input on the Fedora Linux KDE Spin | Shernet. I try to install the packages with : sudo dnf install fcitx5-mozc fcitx5-kkc kcm-fcitx5 fcitx5-autostart but it gives me the following error that I can’t make sense of:

You can try to add to command line:
  --skip-broken to skip uninstallable packages

I’m not sure if this is a Fedora issue or a KDE issue.

I think this is the bug report: 2413564 – F42FailsToInstall: fcitx5-qt5, fcitx5-qt6. You probably need to wait for the maintainer to fix it.

Also, you might not need fcitx5-autostart. This package can cause UI glitches on Wayland. Instead, set the virtual keyboard to use fcitx5 in KDE System Settings after installation.
