[digiKam-users] Success in importing pictures from Android mobile phone

[kaizubg at gmail.com]

Thanks for your tip. Only too bad, it did not solve the issue. The
error message shows up and digiKam is not able to open the connection.

There is one hyphen missing in the command:
"systemctl --user stop gvfs-gphoto2-volume-monitor"
works correctly.
