SUMMARY I imagine this to be the 90% case. STEPS TO REPRODUCE 1. Plug in a USB stick, open it with Dolphin. 2. Launch KPM from the drive's context menu in Dolphin. 3. Right-click the partition and choose “Unmount”. OBSERVED RESULT “Cannot unmount” error dialog, the details only show the command: `umount --verbose --all-targets /dev/sda1`. EXPECTED RESULT Unmounted like Dolphin would do. SOFTWARE/OS VERSIONS Operating System: openSUSE Tumbleweed 20250326 KDE Plasma Version: 6.3.3 KDE Frameworks Version: 6.12.0 Qt Version: 6.8.2 Kernel Version: 6.13.6-1-default (64-bit) Graphics Platform: Wayland ADDITIONAL INFORMATION This breaks the workflow of formatting a previously viewed USB stick from Dolphin.
Hi - following those steps, I cannot reproduce on my Fedora KDE 41 device. Just to check, what filesystem path is being used by your operating system to mount the USB drive? On my device, for example, it's /run/media/username/label Also, what filesystem is used by that USB drive? (ex. exfat?) Thanks!
• Same, /run/media/ilya/Флешка/ • NTFS (via ntfs-3g)
Thanks - for what it's worth, I reformatted my USB drive as NTFS, but still couldn't reproduce on my device. I wonder if something is different about how Tumbleweed is configured? Does running the umount command, as listed in that error message, manually in a terminal work?
$ umount --verbose --all-targets /dev/sda1 umount: /run/media/ilya/Флешка: must be superuser to unmount. $ sudo umount --verbose --all-targets /dev/sda1 umount: /run/media/ilya/Флешка (/dev/sda1) unmounted
