[Bug 1825206] Re: No wifi adapter present in Gnome after upgrade to 0.96-0ubuntu0.18.10.2

[Adam Conrad]

Hello Marc, or anyone else affected,

Accepted netplan.io into disco-proposed. The package will build now and
be available at
https://launchpad.net/ubuntu/+source/netplan.io/0.97-0ubuntu1~19.04.1 in
a few hours, and then in the -proposed repository.

Please help us by testing this new package.  See
https://wiki.ubuntu.com/Testing/EnableProposed for documentation on how
to enable and use -proposed.  Your feedback will aid us getting this
update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug,
mentioning the version of the package you tested and change the tag from
verification-needed-disco to verification-done-disco. If it does not fix
the bug for you, please add a comment stating that, and change the tag
to verification-failed-disco. In either case, without details of your
testing we will not be able to proceed.

Further information regarding the verification process can be found at
https://wiki.ubuntu.com/QATeam/PerformingSRUVerification .  Thank you in
advance for helping!

N.B. The updated package will be released to -updates after the bug(s)
fixed by this package have been verified and the package has been in
-proposed for a minimum of 7 days.

Bug description:
  [Impact]
  Ubuntu users installing from the d-i installer (mini.iso) to set up a desktop, as well as users with complex setups for netplan, managed by both networkd and NetworkManager in multiple files.

  [Test case]
  1) Install ubuntu from mini.iso.
  2) Configure the system normally through the installer up to package selection.
  3) Add GNOME Desktop to package selection and continue install.
  4) After reboot and logging in, check whether the network device configured (wired or wifi) is showing in the GNOME Shell network drop-down at the top of the screen.

  Without the patch, networkd manages the interface and thus it is
  ignored by NM, and doesn't show in GNOME Shell.

  With the fix, NetworkManager manages the interface, it is brought up
  correctly and shows in GNOME Shell.

  [Regression potential]
  This fixes a regression in updates for bionic & cosmic, and a regression that was present in Disco at release time. Since the default renderer effectively changes in this case if there are multiple configuration files listing a different global renderer (the last one configured will be the global default); care should be taken to make sure the interfaces are correctly brought up at boot time.

  This really only affects very specific desktop installs, since they
  may have both NetworkManager and systemd installed from the beginning.
  The default global renderer is always networkd, so the impact of this
  is limited to systems where both: multiple YAML configuration files
  are used with netplan; and both NetworkManager and networkd are used
  as renderer for different network devices. This tends to only happen
  if people have installed from the mini.iso image or if they have made
  the conscious decision to write multiple YAML files and use different
  renderers for different devices.

  Ubuntu release: 18.10 (cosmic)

  I verified this is the culprit after a downgrade to 0.42.2. When I go
  to the Wifi settings of gnome-control-center I get a 'wifi adapter not
  found' message, despite my card appearing in `lspci` and the wifi
  interface appearing in ifconfig.

  My wifi adapter is an Intel Advanced-N 6200, if that is of any help. I
  can provide more details if needed.

  EDIT: I've verified that I can add my wifi credentials to
  /etc/netplan/01-netcfg.yml and after a reboot the wifi connects
  successfully. The only thing not working is the Gnome integration.

  EDIT 2: More details:
  gnome-shell version: 3.30.2-0ubuntu1.18.10.1
  gnome-control-center version: 1:3.30.2-1ubuntu0.18.10.2
