what i have seen in aptus is this..
if you install kde true aptus it install good but the wrong files of kde plasma hahaha..
it needs kde plasma core that is what it needs , if you look after the install true aptus , there is missing like settings for kde plasma that is one...
and its back the same bug in aptus if you unstall it works tru that text blabla ,but if you logout you wil see that plasma is still there so that aptus have 100% a bug 100% no no no 1000%
so what i do i look back in synaptic and yes plasma is still there so i deleted ok, and know i re install kde plasma core and you wil see that the good files where taking automatic , so logout again and enter the kde plasma the good one and that is what it is , but you must fix aptus in every distro from sparkylinux it just dont work if you try to deleted ...
proof of the kde plasma core (this is what the aptus must install , it is the wrong files hahaha...
