Как установить утилиту traceroute? [закрыто]

Я получаю следующее:

atul@ubuntu:~$ sudo apt-get install traceroute
[sudo] password for atul:

Package traceroute is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source

E: Package 'traceroute' has no installation candidate

Кто-нибудь может сказать мне, как решить эту проблему?
