Created attachment 147950 [details] screenshot STEPS TO REPRODUCE 1. mount an ISO image via 'Mount' option from context menu of Dolphin or insert a cd/dvd/bd disc 2. click on 'Disks & Devices" applet in system tray and click on your mounted ISO image or inserted cd/dvd/bd 3. click on 'Reformat or edit with Partition Manager' device action 4. enter your password to open KDE Partition Manager OBSERVED RESULT KDE Partition Manager opens and shows an error. Please see the attached screenshot showing the error that occurs when I reproduce the bug with an ISO image. EXPECTED RESULT 'Disks & Devices' applet should not offer 'Reformat or edit with Partition Manager' device action for devices that can not be formatted nor edited . SOFTWARE/OS VERSIONS Operating System: Arch Linux KDE Plasma Version: 5.24.4 KDE Frameworks Version: 5.92.0 Qt Version: 5.15.3 Graphics Platform: Wayland ADDITIONAL INFORMATION possibly this bug affects other devices like cameras and phones. Not tested with these devices.
I guess we need to check for read-only volumes in desktop file Currently we have [ StorageVolume.ignored == false AND StorageVolume.usage == 'FileSystem' ]
The optical discs case is already fixed in 25.08 branch :) https://invent.kde.org/system/partitionmanager/-/merge_requests/56
'Disks & Devices' applet is still offering the pointless 'Reformat or edit with Partition Manager' option for mounted ISO images. Operating System: Arch Linux KDE Plasma Version: 6.4.91 KDE Frameworks Version: 6.19.0 Qt Version: 6.10.0 Graphics Platform: Wayland
