lxc 1:4.0.2-0ubuntu1 ADT test failure with linux-5.8 5.8.0-1.2

This is a regression in overlayfs for the 5.8 kernel. The same test works fine on an earlier kernel with the same lxc version.

This bug is missing log files that will aid in diagnosing the problem. While running an Ubuntu kernel (not a mainline or third-party kernel) please enter the following command in a terminal window:

apport-collect 1884635

and then change the status of the bug to 'Confirmed'.

If, due to the nature of the issue you have encountered, you are unable to run this command, please add a comment stating that fact and change the bug status to 'Confirmed'.

This change has been made by an automated script, maintained by the Ubuntu Kernel Team.
