I've done some additional tests: installing 'lxqt' and 
'task-desktop-lxqt' both without and with the command line switch 
'--no-install-recommends'.

The package 'lxqt' pulls in 'sddm-theme-debian-elarun' and 'sddm'.
The next bigger package 'task-desktop-lxqt' additionally pulls in 
'kde-config-sddm', 'sddm-theme-breeze' and 'sddm-theme-debian-breeze'

When the switch '--no-install-recommends' is used, 'lxqt' does not pull 
in 'sddm' any more. 'task-desktop-lxqt' has the same sddm-releated 
packages as 'lxqt' without the command line switch.

So the test case of 'task-desktop-lxqt' without 
'--no-install-recommends' is the failing case.

Could the dependency chain in the 'task-desktop-lxqt' package instead be 
changed to mention 'lxqt' before the 'sddm*' dependencies?
I've tested that with live-build, and I get a correct ISO image.

With kind regards,
Roland Clobus
