Public bug reported: There is a Fix proposed from comment 36
https://bugs.kde.org/show_bug.cgi?id=370975 ==== I have this problem when trying to mount any removable device or internal disk partition, either from Dolphin or from removable device manager in panel. It always shows an error message when you try to mount the device first time, the device is not opened in Dolphin but it is mounted correctly. Then at the second attempt it does not show error message and device is opened in Dolphin. The messages that I get in Spanish: >From Dolphin: "Ocurrió un error al acceder a «Carpeta personal», el sistema respondió: El dispositivo ya está montado: Device /dev/sdb3 is already mounted at `/media/yafu/PART 1'." >From removable device manager in panel a window message titled "Error Cliente KIO ?" and "Formato de URL erroneo" message. By the way, in a recent Dolphin update, when you mount partitions from the small folder/home icon to the left of the Dolphin address bar (that icon only appears if you have Panels > Places disabled), every time you Mount a device from there that menu is filled enormously with "Umount <<Partition X>>" items. Really annoying. === Related messages in English: "Error KIO Client" with the text "malformed URL" "An error occurred while accessing 'Home', the system responded: The device is already mounted: Device /dev/sdl1 is already mounted at '/media/myuser/disk title'. ** Affects: udisks2 (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1762163 Title: [Kubuntu 18.04]Device notifier pretends it cannot mount usb device while actually mounting it To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/udisks2/+bug/1762163/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
