Hello.
I got an error when starting this command :
kcmshell5 kcm_desktoptheme
org.kde.kcoreaddons: Error loading plugin "kcm_desktoptheme" "The shared library was not found."
Plugin search paths are ("/usr/lib64/qt5/plugins", "/usr/bin")
The environment variable QT_PLUGIN_PATH might be not correctly set
file:///usr/lib64/qt5/qml/org/kde/kirigami.2/private/globaltoolbar/BreadcrumbControl.qml:63:59: Unable to assign QQuickItem to Page_QMLTYPE_40
file:///usr/lib64/qt5/qml/org/kde/kirigami.2/templates/AbstractApplicationHeader.qml:46:25: Unable to assign QQuickItem to Page_QMLTYPE_40
qt.svg: link XMLID_5_ hasn't been detected!
Effectively the plugin “kcm_desktoptheme” does not exists.
But the desktop “theme editor - System settings module” but nevertheless open itself.
Same kind of error with :
user_install@ASUS-G731GV-JC:~> kcmshell5 kcm_lookandfeel
