re: autopkgtests, please note that while the pending-sru page and 
update_excuses page both show the systemd/i386 test as 'failing', it actually 
passed:
https://autopkgtest.ubuntu.com/packages/s/systemd/bionic/i386

the update_excuses and pending-sru pages appear to be stuck/broken,
possibly due to the recent autopkgtest results url change

the linux-hwe-5.4/i386 autopkgtest still is failing, but it always fails
for everything, so it can be ignored

Title:
  Networkd vs udev nic renaming race condition

Status in systemd package in Ubuntu:
  Fix Released
Status in systemd source package in Bionic:
  Fix Committed
Status in systemd source package in Focal:
  Fix Released

Bug description:
  [Impact]

  systemd-networkd renames nic just after udev renamed it

  e.g

  kernel: [ 2.827368] vmxnet3 0000:0b:00.0 ens192: renamed from eth0
  kernel: [ 7.562729] vmxnet3 0000:0b:00.0 eth0: renamed from ens192
  systemd-networkd[511]: ens192: Interface name change detected, ens192 has 
been renamed to eth0.

  This cause netplan or the other network management pkg can't find
  proper nic sometimes.

  This happens on Bionic

  Below commit seems to solve this issue.
  
https://github.com/systemd/systemd/pull/11881/commits/30de2b89d125a8692c22579ef805b03f2054b30b

  There are bunch of related commits but above one the customer tested
  it worked.

  [Test Plan]

  The customer has issue and they could help us to test this.
  Internally they already test this and it worked.

  Please refer to github issue's reproduction step as well.
  https://github.com/systemd/systemd/issues/7293#issue-272917058
  where the test plan is described as:
  "Reboot a couple of times. Sometimes the interface is renamed correctly. 
Sometimes it is not."

  [Where problems could occur]

  systemd-networkd should be restarted for this patch. systemd-networkd
  nic renaming could have issue. renaming may not be happening
  unexpectedly. e.g doesn't rename it properly or rename it when it
  should do.
