Authentication required to mount /dev/loop0

[digikam at sritch.com]

New laptop running Manjaro + XFCE + DK 8.6.0 QT6 appimage.

I get the following message:

	Authentication required to mount /dev/loop0

- DK will start and work regardless whether I enter my password or
  not.
- DK will only ask for the authentication the 1st time I use DK for
  that day (I shut down the laptop at the end of the day).
- Older Lenovo laptop with opensuse leap 15.6 + XFCE + DK 8.6.0 QT5
  appimage does not ask for the authentication (qt6 does not work).
