Dolphin is giving me the following error:
Unable to create io-slave. klauncher said: Could not find the '/usr/lib/qt/plugins/kf5/kio/file.so' plugin
As a result, Dolphin cannot do anything. I also use Thunar and it works fine. This morning I did a new install of your Plasma iso, the version that is at the bottom of the download page. A wonderful install, and i love being able to choose what software i want to use.
