IPv6 DHCPv6 bug #1543352 in Ubuntu 16.04

[Wido den Hollander]

Hi,

Sorry for coming to the list with this, but I would like to get some attention
for bug: https://bugs.launchpad.net/ubuntu/+source/ifupdown/+bug/1543352

I already worked with upstream to get this fixed and that has been done:
https://anonscm.debian.org/cgit/collab-maint/ifupdown.git/commit/?id=bfca5654959d27603eb50747d9998b92f1d7eb41

How can I get this fix into Ubuntu so that 16.04 properly supports DHCPv6?

Thanks!

Wido
