[Bug 2026826] Re: glib2.0 (2.77.0 ) breaks Netplan build

[Lukas Märdian]

** Description changed:

  Netplan FTBFS as of the latest release of glib2.0 (2.77.0-0ubuntu1) in
  mantic-proposed.
  
  See: https://launchpad.net/ubuntu/+source/netplan.io/0.106.1-3
  
  When I downgrade glib in my sbuild environment, everything works as
  expected:
  
  $ apt install libglib2.0-0=2.76.3-1ubuntu1
  libglib2.0-bin=2.76.3-1ubuntu1 libglib2.0-dev=2.76.3-1ubuntu1
  libglib2.0-dev-bin=2.76.3-1ubuntu1 libglib2.0-data=2.76.3-1ubuntu1
  
  The build also works fine in Debian unstable, which is using glib2.0
  2.74.6-2.
  
  Netplan is using plenty of GLib's keyfile functions
  (https://docs.gtk.org/glib/struct.KeyFile.html), which seem to producing
  a different output with this newer release (some strange line breaks
  injected in the middle of a keyfile).
+ 
+ 
+ Example keyfile from the test_wifis.test_wifi_wowlan test, that should be generated by Netplan and the way it fails:
+ 
+ Expected output:
+ ```
+ [connection]
+ id=netplan-wl0-homenet
+ type=wifi
+ interface-name=wl0
+ 
+ [wifi]
+ wake-on-wlan=330
+ ssid=homenet
+ mode=infrastructure
+ 
+ [ipv4]
+ method=link-local
+ 
+ [ipv6]
+ method=ignore
+ ```
+ 
+ Failure:
+ ```
+ E   AssertionError: '[con[88 chars]330\n\nssid=homenet\nmode=infrastructure\n[ipv[44 chars]re\n' != '[con[88 chars]330\nssid=homenet\nmode=infrastructure\n\n[ipv[44 chars]re\n'
