Hi ! Thank you for the answer. Unfortunately I don't understand why it doesn't work.
I have installed Eric using the official method (virtualenv in ~/eric_env/) I also installed qt5ct. It was complaining QT_QPA_PLATFORMTHEME wasn't set to 'q5ct'. So I have set the env variable (from /etc/environment then restart X session) and the tool doesn't complain anymore. After that, in qt5ct, I choose a dark theme and the preview looks OK. If I open KeepassXC which also use QT5, I can see the changes I make in qt5ct tool is well reflected in KeepassXC. But not in Eric. I'm running Ubuntu 20.04.
