L'installation de docker-engine rend le wifi non détecté

Je suis sur une nouvelle installation 16.10 et j'essaye d'installer Docker dessus. J'ai ajouté le PPA, mis à jour apt et lancé:

Sudo apt install docker-engine

Ça fonctionne parfaitement.

Maintenant, lorsque je redémarre, mon Wifi n'est pas détecté! Il semble que l'interface de menu fixe crée un conflit avec mon interface réseau existante. Il est même en train de le retirer de ifconfig.

Edit: voici quelques commandes sorties avant/après:

$ cat /etc/network/interfaces
# interfaces(5) file used by ifup(8) and ifdown(8)
auto lo
iface lo inet loopback

(idem avant et après)

$ ifconfig -a

La commande suivante ne fait rien non plus:

Sudo systemctl restart network-manager

Je travaille sur un ordinateur portable qui n'a pas de connexion Ethernet, seulement le Wifi.

Le PPA ajouté dans sources.list est:

deb https://apt.dockerproject.org/repo ubuntu-xenial main
networkingwirelessdocker
14
frinux

La recherche indique que cela est probablement lié à ce bogue. Si c'est le cas, une solution de contournement consisterait à modifier /etc/NetworkManager/NetworkManager.conf afin qu'il soit

[main]
plugins=ifupdown,keyfile

[ifupdown]
managed=false

[keyfile]
unmanaged-devices=interface-name:docker0

ce qui obligera NetworkManager à ignorer les adaptateurs de menu fixe.
