I’ve been updating the same system since the first version came out (3 laptops ago). I’ve gone through tons of problems, mostly minor, but a couple of real pains along the way. The last upgrade to 19 from LXDE was not proper at all (it was my doing, didn’t use the Lubuntu distro, just Ubuntu via terminal ) and Ubuntu update didn’t quite know what I had I think… and now I’ve ended up with a Kubunu / Lubuntu hybrid.
It’s all working nicely ( XDG / KDE / GTK / X11 / GNOME ) but it’s taken days to keep things from conflicting or overwriting settings on reboot. So my question is: Does Lubuntu 19 come with KDE/Plasma or am I crazy?
