traceroute in Ubuntu

Question

I'm using Ubuntu 18.04, and I don't have traceroute, even I've just done,

sudo apt-get install traceroute

So I checked, and indeed traceroute package don't have traceroute program:

$ dpkg -L traceroute
/.
/usr
/usr/bin
/usr/bin/lft.db
/usr/bin/traceproto.db
/usr/bin/traceroute-nanog
/usr/bin/traceroute.db

/usr/include/clif.h
/usr/lib
/usr/lib/libsupp.a

/usr/share/man/man1/traceroute-nanog.1.gz
/usr/share/man/man1/traceroute6.db.1.gz
/usr/share/man/man8/tcptraceroute.db.8.gz

How to do traceroute then?
I remember that ping can do it, but didn't find that in a rush.

I do have traceroute6 but, don't know how to use it:

$ traceroute6 172.217.2.165
traceroute: 172.217.2.165: Address family for hostname not supported

FTR,

$ lsb_release -a

Answer 1

It does, right here:

/usr/bin/traceroute.db

There are several traceroute programs for Linux; this is "Traceroute by Dmitry Butskoy". Your own file list also shows a script /usr/bin/traceroute-nanog that emulates "NANOG Traceroute".

You can also find inetutils-traceroute, iputils-tracepath, mtr, and dublin-traceroute.

Note: Debian and Ubuntu have a mechanism called "update-alternatives" which is supposed to pick the best program version out of the ones which are installed, and automatically symlink it to the common /usr/bin/traceroute name. It seems that this mechanism is broken on your system.

Answer 2

try: sudo apt-get install inetutils-traceroute
