Unable to mount USB, Not Authorized

[bman87]

My father just upgraded his laptop from Jaunty to Karmic and has run into an issue when he plugs in his USB flash drive.

When he tries to plug in any USB, he gets the error "Unable to mount USB, Not Authorized"

I am going there after work to check it out, just wondering if anyone has a solution to this.

Here is a screen shot of the error: http://imgur.com/hvGwY.jpg

Thanks in advance.

It's another bug my friend...lead with it the best you can...

Bug 478274

I have the same problem in a minimal karmic install...back to 9.04...i'm a little tired of karmic not working stuff...

Just ran into this in Karmic. Annoying.

Do this:
sudo users-admin, go to Properties > User Privileges and check "Mount user-space filesystems (FUSE)". Log out, log in, try connecting the drive again; it ought to work.

I am having the same problem...

I am running a barebones Karmic install.
(installed command line only, then added fluxbox, nautilus --no-desktop, etc)

How do I change this using the command line? I assume I need to edit the /etc/groups file, but I checked and I am already in the "disk and plugdev" groups that seems to have the permissions to do this.

I have mounted the drive manually using the "sudo umount" command, so maybe the problem is tied in with nautilus?

Thanks

Well, I wish someone had some input for me. I'm still having trouble.

I found this site and followed the recommendations...no dice.

To repeat...I can mount using the command line, but nautilus gives me a permission error.

How do I change the way nautilus handles the permissions of USB drives?

Does Ubuntu Karmic still use HAL? Is that where my problem lies?
I'm willing to do the work and the digging myself, but I need to be pointed in the right direction.

I am having the same problem now. I did not at first, but I changed to a console login using http://ubuntuguide.net/boot-into-con...up-ubuntu-9-10 . Now I cannot mount my usb drive as a normal user. I enabled the root login and was able to mount it that way, but that is not an acceptable ongoing solution..

So my guess is that there is something in gdm, or a related part of the boot process, that grants the permissions. However, Google has not yet led me to the answer.

Hmmmm...

We may be onto something. I am not using gdm. I am currently using nodm to auto login. Now I would think that by using auto login and not having to type in your password could cause this...BUT...when I disable auto login, manually login and then startx.

I have the same exact error message: "Not Authorized"

Could it tie in with the gnome-keyring and nautilus? I think it installs by default, but I don't think I am really using it.

More data: With the drive mounted when logged on as root I got this result for the USB drive when running the mount command.

/dev/sdc1 on /media/Cruzer type vfat (rw,nosuid,nodev,uhelper=devkit,uid=0,gid=0
,shortname=mixed,dmask=0077,utf8=1)

This was after a console logon, and I could not mount the drive as myself--just as root, using the usual Ubuntu configuration of Gnome and Nautilus.

However, this is an old (Pentium 3) machine. Gnome is rather slow, so I replaced it with the Fluxbox window manager, and installed Thunar as an alternative to Nautilus. This time the USB drive mounted correctly for me--seemed to like the minimalist technology As a practical matter I am OK now, but I am still curious about what happened. Apparently Nautilus has some problem here, somehow interrelated with the boot/gdm issue. FWIW, I reran the mount command. The USB drive showed up with

/dev/sdc1 on /media/Cruzer type vfat (rw,nosuid,nodev,uhelper=hal,shortname=winnt,iocha rset=utf8,uid=1000)

I don't know the mount parameters well enough to interpret the results.

Actually, I should test a couple more combinations: Fluxbox/Nautilus and Gnome/Thunar. That will have to wait for another day.

Same problem for me. Any solutions?

Just an FYI, I have dumped GDM because it was causing issues w/ my four monitor setup. I removed it from the startup scripts and am back to the wonderful command line. At the command line I run startx and my world is better. However, I too have discovered the "Unable to mount USB, Not Authorized" problem. This did not happen until I dumped the gdm login screen for the command line. I'll keep looking for a solution too.
