Ubuntu – docker-engine installs makes wifi undetected

dockernetworkingwireless

I am on a fresh 16.10 install, and trying to install Docker on it.
I added the PPA, updated apt, and launched:

sudo apt install docker-engine

It works perfectly.

Now, when I reboot, my Wifi is not detected! It seems docker interface creates a conflict with my existing network interface. It is even removing it from ifconfig.

Edit: here are some commands output before/after:

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

(same before and after)

$ ifconfig -a

The following command is not doing anything either:

sudo systemctl restart network-manager

I am working on a laptop which has no ethernet connection, only Wifi.

The PPA added in sources.list is:

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

  • Research indicates that this is likely related to this bug. If so a workaround would be to modify /etc/NetworkManager/NetworkManager.conf to be

    [main]
    plugins=ifupdown,keyfile
    
    [ifupdown]
    managed=false
    
    [keyfile]
    unmanaged-devices=interface-name:docker0
    

    which will make NetworkManager ignore docker adapters.
