Comment 24 for bug 1740894

As an additional check I once more installed the SRU version (and rebooted):

$ apt-cache policy xkb-data
xkb-data:
  Installed: 2.23.1-1ubuntu1.18.10.1
  Candidate: 2.23.1-1ubuntu1.18.10.1
  Version table:
 *** 2.23.1-1ubuntu1.18.10.1 500

        500 http://de.archive.ubuntu.com/ubuntu cosmic-proposed/main i386 Packages
        100 /var/lib/dpkg/status

Now the problem occurs again. I.e. the first key press still enables the airplane mode just like with the non-SRU version, but the second key press fails to disable the mode:

1.Press key (STILL OK)

-> Airplane mode enables. The airplane mode icon appears in the Gnome panel. Wifi turns off. BT turns off.

2. Press key again (THIS IS NOW BROKEN)

-> Airplane mode appears to disable momentarily: For a short moment the airplane mode icon disappears from the Gnome panel. HOWEVER, then the airplane mode immediately and automatically re-enables. The airplane mode icon reappears in the panel, Wifi and BT remain off.

- does that command works to get out of airplane mode? (Command: gdbus call etc.)

Yes, this still works
