Mount: slave permission denied

Hi, I wasn’t able to build. Log is below:

Failed to make / slave: Permission denied
Error: module john: Child process exited with code 1

I’ve got this from (SSH) dmesg:

[113159.429741] type=1400 audit(1481484020.580:8146): apparmor="DENIED" operation="mount" info="failed flags match" error=-13 profile="lxc-container-default" name="/" pid=79792 comm="bwrap" flags="rw, rslave"

My guess is: this is related to an Ubuntu bug:

A fix was released. Can I check if it was applied in your images?
Thank you
