Well, to me it looks like the apparmor errors are irrelevant.

From this log, I would assume that the dhcp client (PXE) has issues with the DHCPOFFER that it is receiving (or perhaps it cannot see it) as it sends DHCPDISCOVER again and again.

Can you squeeze anything from the faulty PXE node? Did you manage to PXE boot any other machine? -yoctozepto On Mon, Apr 12, 2021 at 2:55 PM Braden, Albert <C-Albert.Braden@charter.com> wrote:

Hi,

Just started a maas+juju deployment on bare metal. I’m facing some errors while PXE booting[1]. Any leads ?
