[Launchpad Bug Tracker <1886790@xxxxxxxxxxxxxxxxxx>]

This bug was fixed in the package lxc - 3.0.3-0ubuntu1~18.04.3

---------------
lxc (3.0.3-0ubuntu1~18.04.3) bionic; urgency=medium

  * Fix tests issue by avoiding falling back to inexistent trusty LXC images
    and using the bionic ones (LP: #1939537)

lxc (3.0.3-0ubuntu1~18.04.2) bionic; urgency=medium

  * Cherry-pick upstream bugfixes (LP: #1848587 LP: #1886790):
    - tests: use /dev/loop-control instead of /dev/network_latency
    - This unbreaks adt-matrix / adt testing of Bionic hwe kernels

Title:
  lxc 3.0.3-0ubuntu1~18.04.1 ADT test failure with B/5.4 kernels
  (device_add_remove_test)

Status in ubuntu-kernel-tests:
  New
Status in lxc package in Ubuntu:
  Fix Released
Status in lxc source package in Bionic:
  Fix Released

Bug description:
  [ Impact ]

   * The device_add_remove_test test fails on the affected series (e.g. Bionic).
   * Having the test fixed for the affected series (for example, Bionic) will allow us to run the LXC test suite without maintaining local changes for this test.

  [ Test Plan ]

   * Run the affected test on an affected series (e.g. Bionic).
   * The test should pass.

  [ Where problems could occur ]

   * The regression risk is very low, and the changes only affect the
  tests, so the regression scope is minimal.

  [ Other Info ]

  The failing test seems to be:

  FAIL: lxc-tests: lxc-test-device-add-remove (0s)
  ---
  Adding /dev/network_latency to the container (device_add_remove_test) failed...
  ---

  This is a regression from the 4.15/5.3 to 5.4 kernels in Bionic. Note
  that this testcase is successful on Focal with the same kernel
  version.
