Comment 21 for bug 1928360

I hadn't realised that they renamed the IM module with the version bump: that means snaps built against older platforms won't load the old (but working) Fcitx 4 module when run on a host system configured with Fcitx 5.

We can certainly look at adding the new IM module to the platform snaps, but that will also switch to the new IPC protocol. From a quick look through the source it will probably be allowed by existing AppArmor rules in the "desktop" interface, but that will need testing.

It's probably going to be easiest to see if we can get things working with a core20 based platform snap though, since we have fcitx5 packages there (albeit for a git prerelease version).

For the core18 based platform snaps, we would need to backport the fcitx5 packages themselves. Alternatively, I wonder if we could get away with symlinking the old module name to the new one?
