Hi!
+ debian/control: Let fcitx5 conflicts with:
- fcitx (<< 1:5)
- fcitx-data (<< 1:5)
- fcitx-bin (<< 1:5)
That may become a bit problematic with respect to package upgrades for users who have both fcitx and fcitx5 installed. I suppose that fcitx5 upgrades will be held back if you just do "apt upgrade".
Ubuntu Kylin 21.10 includes both fcitx and fcitx5 by default. The 21.10 -> 22.04 release upgrade is not so far away.
Not sure what to suggest. To start with I wonder if you have considered situations like the one I mentioned.
