Ich bekomme das:
atul@ubuntu:~$ sudo apt-get install traceroute
[sudo] password for atul:
Reading package lists... Done
Building dependency tree
Reading state information... Done
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
Kann mir jemand sagen, wie ich dieses Problem lösen kann?
