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

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

This is a bug we fixed in our stable-3.0 branch and is fixed in the Ubuntu lxc 3.0.4 packages. See
https://bugs.launchpad.net/ubuntu/+source/lxc/+bug/1848587
and specifically this commit:

    tests: use /dev/loop-control instead of /dev/network_latency

    The latter device has been removed apparently.

Bionic didn't get the 3.0.4 upgrade? That seems odd.

This is a testcase issue, so I'm lowering the importance to 'Medium'.

Observed on B/aws-5.4 , cycle 20210621.

Observed this on B/oracle-5.4, cycle sru-20210621 .

Hello Kleber, or anyone else affected,

Accepted lxc into bionic-proposed. The package will build now and be available at https://launchpad.net/ubuntu/+source/lxc/3.0.3-0ubuntu1~18.04.3 in a few hours, and then in the -proposed repository.

Please help us by testing this new package. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation on how to enable and use -proposed. Your feedback will aid us getting this update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug, mentioning the version of the package you tested, what testing has been performed on the package and change the tag from verification-needed-bionic to verification-done-bionic. If it does not fix the bug for you, please add a comment stating that, and change the tag to verification-failed-bionic. In either case, without details of your testing we will not be able to proceed.

Further information regarding the verification process can be found at https://wiki.ubuntu.com/QATeam/PerformingSRUVerification . Thank you in advance for helping!

N.B. The updated package will be released to -updates after the bug(s) fixed by this package have been verified and the package has been in -proposed for a minimum of 7 days.

All autopkgtests for the newly accepted lxc (3.0.3-0ubuntu1~18.04.3) for bionic have finished running.
The following regressions have been reported in tests triggered by the package:

lxd/3.0.3-0ubuntu1~18.04.2 (i386)

Please visit the excuses page listed below and investigate the failures, proceeding afterwards as per the StableReleaseUpdates policy regarding autopkgtest regressions [1].

Thank you!

autopkgteest & general usage of lxc 3.0.3-0ubuntu1~18.04.3 works with host kernels on bionic's GA kernel and on hwe v5.4 kernels now.

verification done.

cross test of lxd fails, but i386 is not supported under ESM and i'm not sure if i386 cross-arch autopkgtest is valid at all.

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
