# Ubuntu – Authentication required to Mount a Device

mountnautilussudo

Today I came across a very strange message when today i double click the drive WHICH HAS NTFS FORMAT it give me this message THAT AUTHENTICATION IS REQUIRED TO MOUNT A DEVICE I know with root user password u can do this but I have not set the root user password and I don't know the default one.

So can any one tell me how to solve this issue. Graphically and through command Line.

And same thing happen when i tried to install a theme , terminal slapped me with this message " umairmustafa is not in the sudoers file. This incident will be reported."

What on earth is going on.

To confirm if this is your problem, try entering "groups" at a commandline in the terminal. If you don't see either "admin" or "sudo" (one or both), then this is your problem. If you do see one of them, then you may need to directly edit your /etc/sudoers file (as root, of course).
