https://github.com/LeoIannacone/npm2deb/blob/97a4992f4d426a8f04412d85cfa3351fb69bf493/npm2deb/helper.py#L84

While trying to use the rdepends command with a package, it was not working as expected, giving the following output.

test@0c7b0c66ecd8:~/dev$ npm2deb rdepends pretty-ms
Traceback (most recent call last):
  File "/usr/bin/npm2deb", line 7, in <module>

    raise HTTPError(req.full_url, code, msg, hdrs, fp)
urllib.error.HTTPError: HTTP Error 404: Not Found

I further tried to debug the issue by printing the various headers/urls being passed within the traceback and I got this

so I tried to report a bug for this which brought me to the already reported bug https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=905944

So the patch mentioned in the bug above actually makes it work.

I am going to send the PR with the patch next.
