    Cool Unable to automount USB Drive/SD Card under gnome/nautilus

    I am no longer able to automount USB drives and SD Cards under gnome/nautilus. I have tried what I could and have tracked it down (using journalctl -f) to the following gio error code: "Unable to mount volume <volume name>: Gio.IOErrorEnum: Not authorized to perform operation" (please see below for complete error message). It seems that others are also experiencing the same issue, with one user commenting that it started after an update on 13 Nov 2019 - https://askubuntu.com/questions/1190...r-to-mount-usb. I order to track this down, I have done the following:
    1. I can mount it from gnome-disks when run with sudo and properly access my files.
    2. I can mount it as root and properly access my files.
    3. I can mount it with pmount w/o root and properly access my files.
    4. I have used dconf and checked that both org.gnome.desktop.media-handling.automount & org.gnome.desktop.media-handling.automount are both set to true.
    5. I created a new regular user. The USB drive automounts without difficulty. "journalctl -f" reposrts the following: dbus-daemon[8658]: [session uid=1001 pid=8658] Successfully activated service 'org.gnome.Shell.HotplugSniffer'.
    6. I then reset gnome completely (dconf reset -f /org/gnome/).

    But, still, no joy.

    I have been unable to find much on the gio error, and using "gio mount -l -i" shows me info about the drive, but shows nothing as to why I can't access it (complete message below).

    Any help would be greatly appreciated.

    Paul

    This ended up being a strange rights issue. I removed my user account from two groups - vboxusers and chrome-remote-desktop - and now can automount without a problem. I haven't been able to reproduce this issue with a test account as regular user or as administrator.
