Since network-manager 1.2.6-0ubuntu0.16.04.1 was published in the
xenial-updates repository, I think the status can be set to fixed for
xenial.
code:
apt show network-manager 2>/dev/null | grep -E 'Version|APT-Sources'
Version: 1.2.6-0ubuntu0.16.04.1
APT-Sources: http://archive.ubuntu.com/ubuntu xenial-updates/main amd64 Packages
At least for my configuration Dell Inspiron 15 (5557).
