LXD inside LXD - GDBus.Error ... AppArmor policy

Finally got LXD inside LXD working with DIR backend inside ZFS backend.
But now running apt update I got the following error message:

Error connecting: GDBus.Error:org.freedesktop.DBus.Error.AccessDenied: Failed to query AppArmor policy: Permission denied

How do I fix that?
Or does one simply ignore it?
The updating and installing seems to work…
