# the STORE N GO is the USB flash drive

[pavroo]

and how your /etc/fstab looks like?

[piker]

I haven't put an entry for USB flash drives in there:

# /etc/fstab: static file system information.

Just a test - can you comment the line:

Code Select Expand

UUID=5fd5300d-3091-4c1c-b6e2-eaf5e5bd641f   /media/daryl/Backups   ext4   defaults,nosuid,nodev,relatime,data=ordered   0   0
to be not mounted automatically and reboot to check.

[piker]

Ok, did that. I get a "Not authorized to perform operation" message for the Backups drive as well as the usb flash drive now.

[pavroo]

what groups do you belong? run (as regular user):

groups
and what is your desktop you are using now?

#I am using lxqt desktop

[pavroo]

I have to upgrade my lxqt installation now, but ...
Did the mounting work before upgrading, right?
Did you upgrade the kernel too then?

[pavroo]

To have privileges in lxqt desktop, there is 'lxqt-policykit' required, so check is it installed.
Check does it work now, too:

Code Select Expand

pidof lxqt-policykit-agent

[piker]

pavroo.
I just did the "System Upgrade" as normally, via the menu icon. I am now running kernel 4.8.0-1-amd64.
Yes, mounting USB flash drives worked just fine before upgrading.
"pidof lxqt-policykit-agent" returns 1522, so it seems to be installed and working.

[piker]

Possibly found something here:
LXQt session settings -> Autostart
LXPolKit has an exclamation mark and when i hover over it says " Location: /home/daryl/.config/autostart/lxpolkit.desktop    Overrides: /etc/xdg/autostart/lxpolkit.desktop"
# anything in this?

[pavroo]

aaaahhhhh!
How did you install lxqt? via minimalGUI/CLI iso? Let me know, please.

LXQt does not use lxpolkit, your existing lxpolkit.desktop brakes the default one so remove:

Code Select Expand

/home/daryl/.config/autostart/lxpolkit.desktop
LXQt uses lxqt-policykit-agent instead.

Then reboot.

[piker]

I uninstalled lxsession (should I have purged as well?), then found that lxqt-policykit was already installed anyway, rebooted, inserted a usb flash disk and still got the "Not authorized ..." error. However when I clicked on the Removeable media/devices Manager (menu bar)->USBDISK and it opened another session of PcmanFm in which it was actually accessible! (If I already had a PCManFm session running the USBDISK is not accessible).There is still some kind of Permissions problem here somewhere and i'm willing to keep at this if you want to get to the bottom of it completely pavroo, but I do have a useable USB Disk now.
#almost forgot to mention that this was purely a System Upgrade and not a full installation. I've been a happy user of SparkyLinux LXQt for almost a year without issues.

The same is true for me. Unlike Piper, I use budgie-desktop und xfce. Thus neither lxsession nor lxqt-polkit are installed. Everything works fine as long as I do not use a display manager. Have you ever tried that, Piper?

[pavroo]

The budgie desktop uses its own polkit front-end called 'budgie-polkit'.
Check does it work when the Budgie is loaded:

Code Select Expand

pidof budgie-polkit-dialog

The Xfce uses 'polkit-gnome-authentication-agent-1', so make sure is loaded with the Xfce ddesktop:

Code Select Expand

pidof polkit-gnome-authentication-agent-1

According to similar issue with LXQt desktop, check what files exist in your home autostart dir:

Code Select Expand

~HOME/.config/autostart/
