Comment 8 for bug 1798313

Hello!

I just wanted to chime in: My co-worker and I ran into this exact problem. The `traceroute6` command was giving us "sendto: Invalid argument", and we did not have the `traceroute` package installed. It was only by finding this Launchpad bug that we became aware of the problem, after about half an hour of confusion and web-searching.

One other note: In addition to installing the `traceroute` package, we also had to use `update-alternatives`, so that running traceroute (or traceroute6) would go to the executable provided by the traceroute package.

This was really confusing, so I would like to suggest that some sort of action be taken upstream: Maybe a Release Notes item, or some other way to let sysadmins know that the `traceroute6` executable in the iputils package has an important bug (as per the Debian bug entry), and that the workaround is to install the traceroute package, and then use `update-alternatives` to set traceroute's traceroute6 as the preferred traceroute6.
