Hi! Great theme. I am using Sweet KDE theme on all my devices! Lately I tried to install the Sweet KDE and get the error. I find out that the error is related with dependency "Sweet sddm". I tried to manually install the "Sweet sddm", but if I try to download it from here, it is not possible - it shows me download filed "File Incomplete". Can you please check if file is ok? Thanks!
It's a beatiful theme.
For those having problems with QtQuick.Controls 2.5, you should look for the Qt 5 package version >= 5.12
Debian Buster stable, for example, just ships version 5.11
You can try disabling the Clock feature from the source code, commenting or deleting references to the Clock object in the Main.qml file. (I didn't try it)
Unfortunately, the devs don't provide requirement info and users normally run into problems that could be easely avoided.
