As the subject says, with the move from libusb to libusbx I've encountered an issue when upgrading my system with testing enabled: :: Starting full system upgrade... :: Replace libusb with testing/libusbx? [Y/n] y resolving dependencies... looking for inter-conflicts... error: failed to prepare transaction (could not satisfy dependencies) :: usbmuxd: requires libusb>=1.0.8 usbmuxd is required by libimobiledevice, which turns to be required by upower ( and others, but only upower in my system) Any idea on how to proceed from this point?
