Flatpak is a utility for software deployment and package management for Linux. There are two flatpak repository that provides fcitx 5, flathub and fcitx's own unstable repo.

To Setup the flatpak repo, you will need to execute following command, or do it in GUI.

# Add flatub repo, fcitx5-unstable also relies on some runtime packages in it.
flatpak remote-add --user --if-not-exists flathub https://dl.flathub.org/repo/flathub.flatpakrepo
# Optionally: Add fcitx 5 unstable repo if you want to use the unstable version.
flatpak remote-add --user --if-not-exists fcitx5-unstable https://flatpak.fcitx-im.org/unstable-repo/fcitx5-unstable.flatpakrepo

To install fcitx from flatpak

# With older flatpk, you will need to specify the repository name too: flatpak install flathub org.fcitx.Fcitx5
flatpak install org.fcitx.Fcitx5
# Install fcitx 5 engines, for example, fcitx5-chinese-addons, or mozc
flatpak install org.fcitx.Fcitx5.Addon.ChineseAddons
flatpak install org.fcitx.Fcitx5.Addon.Mozc

Flatpak can not provide the im module you need on your host, so you would still need to install them natively. If your distribution does not have fcitx 5 package, you may use fcitx 4 im module instead (newer than 4.2.9.7), or even ibus im module.
