Last day after a small update on my Antergos system with KDE plasma something went wrong and my task manager broke down.
Looking around the task manager and the icons, this error pop up appeared.
Error loading QML file: file:///usr/share/plasma/plasmoids/org.kde.plasma.taskmanager/contents/ui/main.qml:26:1: plugin cannot be loaded for module "org.kde.taskmanager": Cannot load library /usr/lib/qt/qml/org/kde/taskmanager/libtaskmanagerplugin.so: (libprocesscore.so.7: cannot open shared object file: No such file or directory)
After finding the source url posted before I could fix the error.
sudo rm /var/lib/pacman/local/libksysguard-5.14.3-1/ -rf
sudo pacman -S libksysguard --force
