netplan: can't login to ap mode with psk

Here's my netplan config.

I have the same problem as: https://askubuntu.com/questions/1262154/wpa-psk-fails-with-netplan-on-ubuntu-18-04

I just that my uploaded config was wrong. Here's the correct one.

Here's another person asking: https://askubuntu.com/questions/1217858/unable-to-connect-to-netplan-managed-wifi-ap

Turns out NM can't make AP under bridge because it's not passing BridgeIfname: https://gitlab.freedesktop.org/NetworkManager/NetworkManager/-/issues/83

Can be tested here: https://launchpad.net/~shemgp/+archive/ubuntu/testing/+packages for Ubuntu 20.04.*

could you do a merge request upstream for your change?

This bug was fixed in the package wpa - 2:2.9-1ubuntu10

---------------
wpa (2:2.9-1ubuntu10) hirsute; urgency=medium

  * debian/patches/git_dbus_bridge.patch
    - Allow changing an interface bridge via D-Bus (lp: #1893563)

  [ Andrej Shadura ]
  * Security fix: CVE-2020-12695.
    A vulnerability in the UPnP SUBSCRIBE command can trigger the AP to
    initiate a HTTP (TCP/IP) connection to an arbitrary URL or to trigger
    misbehavior in hostapd and cause the process to either get terminated
    or to start using more CPU resources.
    The issue can also be mitigated by building hostapd without UPnP support
    (CONFIG_WPS_UPNP=n) or disabling it at runtime by removing the upnp_iface
    parameter.
    (Closes: #976106)

  * debian/patches/nl80211-Unbreak-mode-processing-due-to-presence-of-S.patch:

The network manager change landed in git master commit ae31b4bf

@seb128, @mhodson, @shemgp, has this patch been submitted to the upstream?

I’ve just verified and in fact not only this hasn’t been submitted upstream, but the upstream has shipped an alternative implementation of this by Beniamino Galvani (@bengal).

I’d really appreciate if Ubuntu didn’t add non-trivial patches without discussion with the upstream and me as the Debian maintainer for this package.

Right, my apologies, I was too quick to be angry: I only checked the patch proposed here but not the actual one committed — and apparently I haven’t read the discussion to the end.

Having checked the actual package, I see it is in fact a patch from the upstream Git.

Still, it’d be great if you could at least notify me, and it would be much better if we could first push such changes into Debian first.

network-manager (1.30.0-1ubuntu1) hirsute; urgency=medium
