The guide has been updated significantly.
I found I had the same problem in getting KDE to theme properly as were mentioned in this thread:
I installed the old Kvantum version because I knew it worked on my other laptop - sudo pacman -S kvantum-qt5 - but when I tried to get it working on my Lenovo laptop it just refused to work. In the end I installed the latest Kvantum version alongside the old one and things magically worked. This was added to the guide…
To get a dark theme on KDE software I found two versions of Kvantum had to be downloaded. Open up the terminal and enter the following to download the required files:
sudo pacman -S kvantum
sudo pacman -S kvantum-qt5
Hopefully it works correctly on all setups.
I also applied the -p flag trick suggested by @BluishHumility to adding the icons and themes folders:
mkdir -p ~/.icons ~/.themes
Big time saver.
Other bits have also been updated.
Hopefully everything works correctly.
