Hello everyone, I encountered an issue with my plasma setup recently after accidentally deleting /usr/lib/qt/qml during an attempt to fix some conflicts. Not finding clear guidance on creating a fresh qml directory with all necessary files led me to share my approach. The goal was to reinstall qt5 and plasma while completely wiping out all existing qml configurations. This would ensure a clean start, though it might affect desktop themes and remove programs like Dolphin, Objection, Konsole, and other KDE applications. In my experience, changing keyboard shortcuts or program settings shouldn't be impacted. The main challenge lies in reinstalling any themes you previously downloaded from the AUR. Just reinstalling plasma and qt5 isn't sufficient because it won't replace the corrupted qml files, so the entire system stack needs to be cleared. To remove qt5 and plasma along with any damaged settings, run pacman -Rcns plasma qt5 (this is specific to Arch Linux; adjust for Debian or RHEL accordingly). After that, reinstall both packages and any removed programs such as Dolphin, Objection, Konsole, and most KDE tools. Before proceeding, ensure you have a terminal emulator independent of KDE installed, as Konsole will also be gone and reinstalling everything could become more complicated without a terminal, particularly if you're on Wi-Fi. I hope this helps someone facing a similar situation.
