( Solved) Error mounting shared Folder

[dimele]

Hello,
I have a KUbuntu 14.04 guest.
I am trying to mount a shared folder but I have the followed error:

Code: Select all

mount: wrong fs type, bad option, bad superblock on VmShare,
       missing codepage or helper program, or other error
       (for several filesystems (e.g. nfs, cifs) you might
       need a /sbin/mount.<type> helper program)
       In some cases useful info is found in syslog - try
       dmesg | tail  or so

The command

Code: Select all

dmesg | tail 

gives the following result:

Code: Select all

Please, what is going wrong?

did you add yourself to the vboxsf group?

if not, open Konsole and type...

Code: Select all

sudo adduser user vboxsf

replace 'user' with your login name.
restart Kubuntu.

Yes I did.

Yes I did.

well, then you have run into a bug that is in VB 4.3.10 which will be fixed in the next version. In the mean time, in VirtualBox with Kubuntu shutdown, delete the shared folder from "Shared folders". Re-add the folder you want to share but select auto-mount, start Kubuntu, the shared folder will be in /media.

It works!!!!!
I had the same problem with XUbuntu. I test the solution and it works too.
Thanks to you.
