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

Mon May 20 08:47:57 UTC 2019

This bug was fixed in the package netplan.io - 0.97-0ubuntu1~18.04.1

---------------
netplan.io (0.97-0ubuntu1~18.04.1) bionic; urgency=medium

  * Backport netplan.io 0.97 to 18.04. (LP: #1828299)
  * Keep patches specific to 18.04 support:
    - glib_changes.patch: fixes for older GLib version
    - disable-networkd-tunnels-ipip-gre.patch: disable tests for unsupported
      tunnel types (ipip and gre) in the 18.04 version of systemd-networkd.

netplan.io (0.97-0ubuntu1) eoan; urgency=medium

  * New upstream release: 0.97
    - networkd: force bringing up devices with no IP addresses (LP: #1763608)
    - Reworked renderer choosing to avoid regression in default renderer when
      multiple files specify it globally (LP: #1825206)
    - Fixed networkd activation. (LP: #1821867)
  * Drop all patches; they are included in the upstream release.

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
