Bug Description

After updating to 1.12.4-1ubuntu1, several Lubuntu users have reported WiFi is broken. I can reproduce this with one of my laptops.

Bringing the connection up with nmcli reveals this:

$ nmcli connection up id MY\ SUPER\ SECRET\ SSID
Error: Connection activation failed: The Wi-Fi network could not be found

After downgrading to 1.12.2-0ubuntu5 and running `sudo systemctl restart network-manager.service`, the WiFi connects without issue.

My next step is going to be to confirm this with other flavors; if it's a generic issue, the next step will be trying to bisect where this went wrong.

Oh, wonderful, so I can't reproduce it under Kubuntu.

I'll still keep this open against network-manager though, because I can reproduce it with nmcli under Lubuntu. So, I'll Git bisect the bad change in network-manager.

And, now I'm confused, because after a reboot it works fine.
