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:
commit 11fc6882f7bfd40fbcda6a3a7f7c1bca50df3f2b Author: Christian Brauner <email address hidden> Date: Mon Nov 18 15:08:22 2019 +0100
tests: use /dev/loop-control instead of /dev/network_latency
BugLink: https://bugs.launchpad.net/bugs/1848587
The latter device has been removed apparently.
Bionic didn't get the 3.0.4 upgrade? That seems odd.
