I am going to guess it is looking for Plasma 5 versions, if not from 5.24. It looks like neon don’t package this, so the version installed is from Ubuntu.
$ apt policy kile
kile:
Installed: (none)
Candidate: 4:2.9.93-2
Version table:
4:2.9.93-2 500
500 http://archive.ubuntu.com/ubuntu jammy/universe amd64 Packages
100 /var/lib/dpkg/status
I wonder if the neon team can be prodded to add this?
