I’m on Debian Testing and receive this strange message when open Dolphin today, if I not forget when I upgraded some kde packages were upgrade. Unable to create io-slave. klauncher said: Error loading ‘/usr/lib/x86_64-linux-gnu/qt5/plugins/kf5/kio/file.so’. Please tell me how can I solve this issue.

Debian is a free operating system (OS) for your computer. An operating system is the set of basic programs and utilities that make your computer run. Debian provides more than a pure OS: it comes with over 59000 packages, precompiled software bundled up in a nice format for easy installation on your machine.
