network-manager autokpgtest failure (nm.py)

[Roxana Nicolescu]

This fails only on arm64.

https://autopkgtest.ubuntu.com/results/autopkgtest-lunar/lunar/arm64/n/network-manager/20230522_141200_71ac4@/log.gz

To be determined if there is a bug in the package or linux kernel.

Status changed to 'Confirmed' because the bug affects multiple users.

As far as I can see, the only tests failing now are related to differences in MAC addresses on veth interfaces. I created an MP to address these failures. See more details in the related MP.

Thank you for your investigation. This sounds very related to this systemd/udev quirk:

This bug was fixed in the package network-manager - 1.44.2-1ubuntu2

---------------
network-manager (1.44.2-1ubuntu2) noble; urgency=medium

  [ Lukas Märdian ]
  * network-manager.postinst: Skip unknown connection profiles (LP: #2039503)
  * d/network-manager.postinst: Drop reboot notification (LP: #2040292)

  [ Danilo Egea Gondolfo ]
  * debian/tests/nm_netplan.py
    Start Network Manager via systemd. The .service unit file sets
    ProtectSystem to true and we want to run the Netplan tests with this
    restriction enabled.
  * d/p/netplan/0003-Allow-the-NetworkManager-daemon-to-write-to-lib-netp.patch
    Allow-list /usr/lib/netplan so libnetplan can open files from that
    directory with writing permission. See LP: #2040153
  * debian/tests/control
    Add all the dependencies required by the nm_netplan.py tests.
  * debian/tests/network_test_base.py.
    Increase the waiting time between creating a veth pair and reading their
    MAC addresses. On arm64, the system is taking longer to change the MAC
    after creation, leading to failures due to differences in the expected
    and current MAC addresses. See LP: #2023183
