[Bug 1848225] Re: netplan fails to configure wifi on rpi4 with eoan

[Paul Larson]

Marking invalid - after further investigation it turned out to be an
ordering problem where some network-manager tests  ran before the
netplan tests. Deleting a connection in network-manager doesn't seem to
clean up after the wpa-supplicant sockets that it creates, resulting in
two of them existing for the same interface when netplan tried to start
things up.

Title:
  netplan fails to configure wifi on rpi4 with eoan

Status in netplan.io package in Ubuntu:
  Invalid

Bug description:
  I was able to successfully configure wifi with NetworkManager, but if
  I try to configure it with netplan it doesn't seem to work.

  I've also tested this on rpi3b+ with eoan and it worked fine there.
  To test this, I ensured all networkmanager connections for wifi were deleted, and that it was in an unconfigured state. Then I added this to /etc/netplan/99-netplanbg.yaml:
  network:
    version: 2
    wifis:
      wlan0:
        access-points:
          ubuntu-cert-bg-open-tpelab: {}
        addresses: []
        dhcp4: True
        nameservers: {}

  (I've also tried this with other test networks of bg/n/ac and open/wpa - none work for me)
  After running 'sudo netplan apply', I see in networkctl that it goes into a "configuring" state, but it never goes to configured/routable and never gets an ip address.
