Some Netplan-related autopkgtests are failing on armhf

[Danilo Egea Gondolfo]

The root cause appears to be NM not being ready yet when the test starts.

# /usr/bin/python3 /tmp/autopkgtest.kW7u4i/build.K7E/src/debian/tests/nm_netplan.py
test_nmcli_add_device_and_change_it (__main__.TestNetplan.test_nmcli_add_device_and_change_it)
Uses the nmcli to add a connection and validates if the ... Warning: nmcli (1.44.0) and NetworkManager (Unknown) versions don't match. Restarting NetworkManager is advised.
Error: NetworkManager is not running.
FAIL

We need to wait until Network Manager is ready before starting the test.

Well, actually, there are tests from nm.py failing for the same reason...

I'm running some tests with the linked MP.

Both tests that require building a kernel module are failing due to the new default gcc

The patch helped with nm.py and nm_netplan.py tests but the ones that require building kernel modules are still failing due to the gcc version.

This bug was fixed in the package network-manager - 1.44.0-1ubuntu2

---------------
network-manager (1.44.0-1ubuntu2) mantic; urgency=medium

  * d/t/{nm.py,nm_netplan.py,network_test_base.py} (LP: #2033391):
    - Wait until NM is ready before starting tests
    - Add a delay loop checking if NM is already on-line before running each
      test.
  * d/t/nm.py: remove expectedFailure from both tests in Hotplug.
    - It's not clear why they were expected to fail. With NM 1.44.0 they are passing.
    - As this class states that the APs are set up with NM already running, in
      test_auto_detect_ap() self.start_nm() was moved to run before
      self.setup_ap() and the assert was fixed to get the actual gobject data.
