i'm facing a problem when try to mount my USB hardisk:-

nio@niomachine:~$ sudo apt-get install ntfs-3g-nautilus-tools
Reading package lists... Done
Building dependency tree... Done
Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.

Since you only requested a single operation it is extremely likely that
the package is simply not installable and a bug report against
that package should be filed.
The following information may help to resolve the situation:

The following packages have unmet dependencies:
ntfs-3g-nautilus-tools: Depends: nautilus-script-manager but it is not installable
Depends: libnotify-bin but it is not installable
E: Broken packages

any clues???
