I have couple of questions regarding Snappy Core 16.04. I have been playing around with it for a while and have couple of concearns:

  1. How to use network-manager ? There is a snap provided by canonical called network-manager but when using nmcli it does not work.
  2. Readonly file system: Iw ould like to enter my wlan SSID and password in interfaces but the file system is write-protected how to deal with it (in general - i eman editing linux config etc)

Regards

  • As snappy is something new and they build it up "completely from the ground", we should expect alot to work differently. About your questions: ad 1. the command would be network-manager.nmcli ad 2. the command might be wireless-tools.iw plus I once by accident stumbled over some plans by "them" to use netplan for managing your network devices and then passing them on to all the kind of handlers like network-manager. – db429 Nov 12 '16 at 21:37
  • see my tutorial at askubuntu.com/questions/585790/… and see if you can configure your wifi that way – Burly Ares Feb 24 '17 at 5:24

I got my wifi setup working using network-manager. In essence:

# Install Network Manager using Snap
sudo snap install network-manager

# Turn on the WiFi interface
network-manager.nmcli r wifi on

# verify the WiFi is on
network-manager.nmcli r

# List the available network
network-manager.nmcli d wifi list

# Connect to a network
network-manager.nmcli d wifi connect <ssid> password <password>

# verify it is connected to WiFi
network-manager.nmcli c

That should be it. I put it together in gist.
