“No object for D-Bus interface” when mounting with Nautilus

Question

I have an internal HDD that gives this error when I try to mount either of its two partitions in Nautilus, while my main HDD works fine.

When I use Disks to mount it works but unmounting in Nautilus gives the same error. mount works too.

dmesg and syslog shows nothing special, so I don't know where to look for the relevant log. I hope someone can provide me some hints on this issue.

Answer 1

Apparently this question appeared on Google and many people are asking me to post an answer, so here it is.

1. First, go to Dash (for Ubuntu) or run gparted using superuser, preferrably gparted-pkexec.
2. Right click the partition, choose New UUID.
3. Click the Apply button.

This solution should be permanent until you mess something up, so no worries.

Answer 2

I have temporary solution, try mounting with

sudo mount /dev/... /mnt/tothisdir

Or use "Disk" to mount or any other but not nautilus

Answer 3

Unmounting gvfs solved the problem for me:

umount -fl /home/user/.gvfs
rm -rf /home/user/.gvfs

I found that solution here

Answer 4

If botchniaque's fix doesn't work for you, first check the gvfs mountpoint on your system:

mount | grep gvfs

On Ubuntu 15.10 it was mounted under /run/user/[USER ID]/gvfs, so the following commands worked for me:

sudo umount -fl /run/user/[USER ID]/gvfs
sudo rm -rf /run/user/[USER ID]/gvfs

Answer 5

For me none of the mentioned solutions worked out. Or at least they did not work immediately.

However, after I rebooted the machine, the drive worked.

So I don't know, whether a simple reboot fixed it or the umount/rm -method and a reboot after those.
