when I try to connect a ntfs formated disk, I'm getting this message:

Error mounting: mount exited with exit code 1: helper failed with:
Error opening ' /dev/sdb1': Permission denied
Failed to mount '/dev/sdb1': Permission denied
Please check '/dev/sdb1' and the ntfs-3g binary permissions,
and the mounting user ID. More explanation is provided at
http://ntfs-3g.org/support.html#unprivileged

mounting other formats (i.e. fat, ext) works just fine

I checked that I'm in the right groups (at least it looks right)
cs@pikass:~$ groups
cs cdrom floppy tape sudo audio dip video plugdev staff users netdev bluetooth
lpadmin fuse scanner

permissions for /dev/sdb1 seems to be correct
cs@pikass:~$ ls -l /dev/sdb*
brw-rw---- 1 root floppy 8, 16  7. Jan 11:03 /dev/sdb
brw-rw---- 1 root floppy 8, 17  7. Jan 11:03 /dev/sdb1

I even tried to set a uid bit (4755) on ntfs-3g, as suggested by http://ntfs-
3g.org/support.html
then I'm at least able to mount the device via shell as a normal user, but it
doesn't solve the problem in gnome (and it's na ugly hack)

It seems to apply only for amd64, since I performed two squeeze installations
in the last weeks.
The first was around the 16th of december 2010 on an i386er machine as a test
and two days ago another one as amd64. Automounting ntfs drives in Gnome on the
i386 installation works just fine but not on the amd64 machine.

cheers, Christian

reassign 609201 udisks
tag 609201 unreproducible
thanks

The mounting itself is done by udisks, which is privileged, not by gvfs.

So there is nothing wrong on the permissions side.

Indeed.

This is useless for mounting with udisks.

This is certainly unrelated to the architecture, but might be caused by
either a local misconfiguration or a missing package. I can definitely
not reproduce this on my amd64 machines.

I installed freshly Debian 6.0 and was surprised that I am unable to mount
my ntfs formatted Seagate FreeAgent Go external usb drive. I have done
everything what I could,

- added myself to floppy group
- I changed permission of ntfs-3g to setuid root
- Installed hal and hal-info (they were missing, wow), and gvfs-fuse (which
were also not installed)
I had no luck, and the problem is still there. I decided to reboot to do
some things in Windows, after I came back and login, a popup message told me
that I just had a kernel oops :S I saved my dmesg and dropped to pastebin:
http://pastebin.com/gF4qD4ub
Ok, lets do a bit rollback - because I did not have that before- , purged
gvfs-fuse and the kernel oops is gone :) You can see that here:

I seem to be running into the same issue as Christian. Upon plugging in
a ntfs usb disk I get the same gnome window that pops up:

Error mounting: mount exited with exit code 1: helper failed with:
Error opening '/dev/sdb1': Permission denied
Failed to mount '/dev/sdb1': Permission denied
Please check '/dev/sdb1' and the ntfs-3g binary permissions,

It looks like I'm in the correct groups (correct me if I'm wrong).

fes@fes-laptop:~$ groups
fes adm disk cdrom floppy audio dip video plugdev netdev bluetooth
lpadmin fuse scanner

Mounting manually on the commandline with sudo works fine.

This happens on a freshly installed squeeze i386 system.

I was able to fix this. Apparently the installer added a line to
/etc/fstab which I had not noticed:

/dev/sdb1       /media/usb0     auto    rw,user,noauto  0       0

I assume that this was the usb flash drive connected to my laptop during
the installation. This was necessary to include some firmware files for
my wireless card.

Removing the line above from /etc/fstab resolved the issue for me.
Plugging in an external usb drive automatically mounts now.

Hope this helps someone else out.

Cheers,

Frederic

I have to agree with Frederic. I made a fresh install with xfce desktop, and
I pulled out my usb hdd before the installation started.
After installation finished, there wont be any noticeable problem.
Everything works fine !

I recently installed a weekly build from
http://cdimage.debian.org/cdimage/weekly-builds/ by booting from a USB stick,
and was also affected by this bug.

I assume this means that anyone doing a USB installation will also be
affected. This make the bug quite serious IMHO.

Regards,
Scott.

Imho, d-i shouldn't write fstab entries for USB sticks during installation.

d-i team: would it be possible/feasible to change this behaviour?

stick,
installation.

Can same fix be applied to this new issue?
