SUMMARY When loopback device is unmounted, it is still listed in device list. This is caused by it not being detached. If you run "losetup --detach-all", it gets removed as expected It could be KIO issue but I am facing it only using dolphin, so there's that. STEPS TO REPRODUCE 1. Mount loopback device (e.g. by using Mount option on ISO image file) 2. Unmount device OBSERVED RESULT Device still in device list EXPECTED RESULT Device removed after unmounting SOFTWARE/OS VERSIONS Operating System: Arch Linux KDE Plasma Version: 5.27.7 KDE Frameworks Version: 5.109.0 Qt Version: 5.15.10 Kernel Version: 6.1.49-1-lts (64-bit) Graphics Platform: X11
