Error in 17.10: RTNETLINK answers: Invalid argument. Needs 1.4 version from github.

# Description
Wondershaper is not working as expected in my Ubuntu 17.10, kernel 4.13.0-25-generic, x86_64.

Similar to https://bugs.launchpad.net/ubuntu/+source/wondershaper/+bug/1739086 , but in my case the connection speed remains normal. Wondershaper is working for me in Ubuntu 16.10.

This user reports the same problem: https://askubuntu.com/questions/922152/limit-internet-bandwidth-17-04 . Sadly, it has been tagged as a duplicate question, but it is not.

wondershaper is very old, not maintained since Mon, 11 May 2015
http://repo.or.cz/lartc.git

Its clearly proposed to now use iproute2 instead
http://lartc.org/wondershaper/

So that old package should better be removed from archive

[aguadopd (aguadopd)]

@9d9 I don't understand why you mark it as incomplete. How can I complete it? Maybe the solution is to remove the package but until then, the bug is there.

Neither `iproute2` nor `tc` or other options mentioned in related questions are as easy to use as `wondershaper`. I mean, `wondershaper` can be used with a single and simple command; the most difficult part for the user is to discover the name of the interface he wants to limit/shape.

Status changed to 'Confirmed' because the bug affects multiple users.

Same problem on 16.04 LTS with HWE kernel.

Some good news: new version 1.4

" Wonder Shaper was first released by Bert Hubert in 2002, but the original version lacked a command-line interface, from on version 1.2 this feature was added. From version 1.3, the HTB queing is used instead of CBQ, allowing better bandwith managment on high speed (above ten megabits) links. In version 1.4 an improved ingress shaping method was implemented and the ability to limit either down or up (both is still possible too). "

https://github.com/magnific0/wondershaper/

So the Debian source link should be updated, to get the latest package's changes, and finally be synced with ubuntu archive.

[aguadopd (aguadopd)]

As @9d9 reports in comment #5, there is a working updated script in https://github.com/magnific0/wondershaper

This was not working for me before, but it is now with Linux 4.13.0-32-generic. Maybe a system reboot did the fix. See the conversation here: https://github.com/magnific0/wondershaper/issues/17

Maybe one day the Debian package is updated.

I'm having a little trouble reconciling where exactly to request the change, but I think the upstream package source is from github and I just logged an issue there:

https://github.com/leggewie-DM/wondershaper/issues/1

I can confirm that if you simply download the wondershaper from the magnfic0 repository, things work fine. If that script could be used as the upstream source then patched up for Debian standards (relocate to /sbin etc) then the ubuntu repositories would contain a wondershaper that worked as expected
