Updating today I had this:
error: failed to prepare transaction (unable to satisfy dependencies)
:: installing kvantum (1.0.10-2) breaks the "kvantum-qt5" dependency needed by kvantum-theme-adapta
:: installing kvantum (1.0.10-2) breaks the "kvantum-qt5" dependency needed by kvantum-theme-matcha
kvantum-theme-matcha is required by manjaro-xfce-settings.
*kvantum-theme-adapta I can uninstall
